Chapter 8. The X-DOS Shell Program Introduction X-DOS provides a shell utility called XSHELL. The XSHELL program is a special extension of the X-DOS operating system that provides an easy to use menu driven interface. With XSHELL you can carry out all your file management tasks using simple pull down menus rather than having to remember lots of complicated commands. The shell program is completely mouse driven too, so you can move around the screen by clicking the mouse where you want to go and run commands by clicking on them in the menus. For added convenience the DOS command line is still visible in the shell and you can type in and run commands from the command line just as normal. In addition, XSHELL provides a split screen display allowing you to display two different directories on the screen simultaneously and the files in those directories. XSHELL also includes a special file application function which allows you to set up menus from which you can run your favorite programs simply by clicking on the program name with the mouse. Once you get used to using XSHELL you may decide that you wish it become the default screen display every time you load X-DOS. In that case you can enter a command in your AUTOEXEC.BAT file to automatically load XSHELL when you turn your computer on or set the automatic XSHELL boot in the INSTALL program. Setting The XSHELL Path If, for some reason, you have moved the SHELL overlay files to another directory than the DOS directory on the boot drive, you must tell X-DOS where they are located. If, for example, you decide to store the XSHELL overlay files in the \DOSSHELL directory, you must type the following command at the DOS prompt: SET XSHELL=C:\DOSSHELL This tells X-DOS to look in the DOSSHELL directory on the C: drive for XSHELL. The statement you actually type may differ from this example depending on which drive and in which directory you have installed X-DOS. You should enter this statement in your AUTOEXEC.BAT file so you do not have to type it every time you wish to use XSHELL. Loading XSHELL 8-1 To load XSHELL simply boot up your computer with X-DOS, set the shell path as described above if you have moved the SHELL files form the default directory (if you have entered this statement in your AUTOEXEC.BAT file you will not have to do this) and type HS or XSHELL at the command line. Loading XSHELL Switches Two switches are available with XSHELL to allow you to go directly to the File functions mode or Applications mode. The File functions mode is the default XSHELL mode in which you can carry out your file management. The Applications mode allows you to create a menu list of your programs and run these programs with the click of a mouse. To load XSHELL in the default mode, at the DOS prompt type: HS /F or just HS. You can also use the XSHELL name. To load XSHELL in the Applications mode, type: HS /A The XSHELL File Management Screen Display When in the file management mode, the XSHELL display consists of a number of different areas, with each area containing important information. Along the top of the screen is a list of the menus and the function keys that access them, as listed below: F1 - Help F2 - File F3 - Disk F5 - Applications F6 - Split F7 - Zoom In the main portion of the screen are four windows. The two windows on the left show identical directory trees for the drive from which you loaded XSHELL. The volume label of the drive will also be shown. If no volume label was assigned to the drive "None" will be displayed. The two windows on the right display identical lists of the files contained in the directory from which XSHELL was run. Each window also shows the number of files in the current directory and the number of bytes of unused space on the disk. In the bottom area of the screen, on the left is a list of the drives installed on your system, with the current drive highlighted. In the center is written 0 Files marked, and on the right 0 Bytes. In the bottom left corner of the display is the DOS prompt with a blinking cursor. Using XSHELL With a Mouse If you have a mouse installed on your system you will find it extremely convenient to move around XSHELL and run commands. 8-2 Calling Up Menus To call up a menu, simply move the mouse cursor over the menu name and click the left mouse button. Running Menu Commands To run a menu command, simply move the mouse cursor over the command you wish to execute and click the left mouse button. Many of the menu commands require that you first select a file or group of files to run this command on. If you click on a menu item that requires file to have been selected the message No File(s) are Selected will appear. Selecting the Active Window To move between the windows in the main screen area, simply move the mouse cursor to the window you wish to select and click the left button. The selected window will become the active window which is always surrounded by a double lined box. Selecting and De-selecting Files To select a file for a certain action such as copying or deleting, simply click on the file with your mouse. A marker will appear next to this file indicating that it is currently selected. You may select as many files as you want in this way to perform actions on multiple files. To deselect a selected file simply click on that file a second time. The Command Line If you wish to enter a DOS command at the command line, simply type the command on your keyboard in the normal way and the command will appear at the command line in the bottom left corner of your screen. When ever you type anything on the keyboard, assuming you have not called up any menu functions, this will automatically appear at the command line. To run any command typed in at the command line, simply press [Enter] just as you do when not running XSHELL. You can recall the previous command by pressing the F10 key. Using XSHELL With the Keyboard If you do not have a mouse you can still access all the XSHELL functions from the keyboard. Calling Up Menus To call up a menu, simply press the relevant function key as listed against the menu names at the top of your screen. For example, to call up the Help menu, press F1; to call up the File menu press F3. Running Menu Commands To run a menu command, simply move the highlight bar over the command you wish to execute with the cursor up/down keys and press [Enter]. Many of the menu commands require that you first 8-3 select a file or group of files to run this command on. If you run a menu item that requires file to have been selected the message No File(s) are Selected will appear. Selecting the Active Window To move between the windows in the main screen area, press the [Tab] key. This will move you between the windows on your screen clockwise. The active window which is always surrounded by a double lined box. Selecting and De-selecting Files To select a file, use the cursor up/down keys to move the highlight bar over the relevant file and press [Enter]. You may select as many files as you want at the same time to perform functions on multiple files. To deselect a previously selected file, highlight that file and press [Enter] a second time. The Command Line If you wish to enter a DOS command at the command line, simply type the command on your keyboard in the normal way, press [Enter] and the command will be executed. Guide to General Usage From within the shell you can carry out all your file management functions, such as copying and deleting files etc., creating directories, sorting files within directories and generally manipulating all the data stored on your disks and diskettes. In addition, the utilities menu includes many special functions including a number of security features and a file transfer utility which allows you to transmit data from your computer to another computer via the serial interface. When you first enter XSHELL your screen is divided into two pairs of identical windows. Whenever you want to perform an action on a file, first click on the window containing that file information, and then click on the file to mark it. You may then click on the File menu and select the item of your choice, such as Copy or Delete. To select multiple files, simply click on several files. Each selected file will be marked. Note that at the bottom of your screen the number of files currently marked will be shown and the total number of bytes comprising those files. To display the directory tree of two different disks on your screen, simply go to the Disk menu, click on Change Drive, click on the drive letter to which you wish to change or type the drive letter on the keyboard, and the active window will change to displaying the directory tree of the new drive. The other directory window will still show the directory tree of the original drive and you have a clear visual image of the 8-4 directories and files on two different drives. Use the Split and Zoom functions to change the screen display to show just one directory and file window and to zoom in on one window, allowing a full screen display of that window. Both the Split and Zoom functions are instantaneous - click on them once to change the screen display and click on them, a second time to go back to the original display. For a full reference of all the commands in XSHELL please refer to the XSHELL Command Reference, below. XSHELL Command Reference XSHELL consists of an application management section and a file management section. Each section has a menu bar from which most of the XSHELL functions can be accessed. To call up a menu press the function key allocated to that menu or click the left mouse button with the mouse cursor on the menu name. Get further information on any of the menu bar items below by selecting them and pressing F1 to call up help. This reference section is divided into two parts. The first part deals with the File Management function of XSHELL; the second part explains how to use the Application function. The Menu Bar in the File Management Section of XSHELL: F1-Help Displays context sensitive help everywhere in XSHELL. F2-File Activates a pulldown menu with file related functions. F3-Disk Activates a pulldown menu with disk related functions. F4-Utilities Activates a pulldown menu with several utilities. F5-Applications Loads the application section of XSHELL. F6-Split Toggles between double and single directory display. F7-Zoom Zooms in on the active window. The F2-File Pulldown Menu You can display the F2-File pulldown menu from the menu bar in one of two ways. Either click on the menu with your mouse or press F2. The pulldown menu contains the following functions: 8-5 Run File AltR Copy File(s) AltC Move File(s) AltM Delete File(s) AltD Locate File(s) AltL Rename File(s) AltN Edit File(s) AltE View File(s) AltV Compare Files AltO Print File(s) AltP Change Attributes AltA About XSHELL AltI Select Group AltS Unselect Group AltU Gateway to DOS AltG Exit XSHELL AltX The F3-Disk Pulldown Menu The F3 pulldown menu contains the following functions: Add Directory Delete Directory Rename Directory Change Drive Format Diskette Make Bootable Disk Copy Diskette Check Disk Search Disk for Text Name/Rename Volume Backup/Restore The F4-Utilities Pulldown Menu The F4 pulldown menu contains the following functions: Memory Status Re-read Tree Security Features Setup Peripherals System Time/Date 25/43 Line Display Window Switch File Display Format Display Filter Recall DOS Line Directory Sort Undelete File(s) Format Recovery Communications Program File Transfer Link Extension Associations 8-6 Save Configuration The F5-Applications Menu Item This menu activates the Application section of the shell. The F6-Split Menu Item This function toggles the one/two drive format of the XSHELL windows. The F7-Zoom Menu Item This function will zoom the drive window to show one drive only but will leave the two directory windows on the right. File Application Function Command Reference This section contains a reference of all the menu commands in the file application section of XSHELL. The file application section is the default display when you enter XSHELL. File Menu Functions (F2) Run File The Run File menu item executes a selected file. You must first select a file before you can choose to execute a program. Place the selector in the right portion of the screen over the file you wish to execute. This function can only execute files with an extension of .EXE, .COM or .BAT Upon execution, or with an automatic file extension association. XSHELL will release all of the memory occupied by itself so that you have plenty of room to run even large application programs. When you exit the application program, XSHELL reloads itself and returns you to the file management main screen. You may enter parameters in the provided window before the application is activated. Hot Key: AltR You can double click on a file with a mouse to run it. Copy File(s) The Copy File(s) menu item makes it easy for you to copy one or more files between different directories, even across different drives. You select files in the highlighted directory window then copy the files to a destination of your choice. By default, XSHELL prompts you with the directory of the second window. Hot Key: AltC Move File(s) The Move File(s) menu item makes it easy for you to move one or more files between different directories, even across different drives. The selection principle is similar to the copy files function. 8-7 Hot Key: AltM Delete File(s) The Delete File(s) menu item lets you delete one or more selected files from the active file window. If you accidentally delete files which you did not intend to delete, you can use the Undelete File(s) menu item in the F4-Utilities pulldown menu to recover the deleted file(s). Hot Key: AltD Locate File(s) The Locate File(s) menu item lets you find the location of a file or range of files anywhere on a drive. XSHELL offers the option to view the files found. This function only works for the drive selected by the left highlighted window. Hot Key: AltL Rename File(s) The Rename File(s) menu item allows you to rename one or more files. You must specify a name which does not already exist on the current directory. Hot Key: AltN Edit File(s) The Edit File(s) menu item lets you edit the contents of a file or range of files. The files you want to edit must be ASCII text files. This function calls the X-DOS editor ED. Hot Key: AltE View File(s) The View File(s) menu item lets you display the contents of a file or range of files. You can scroll in the file and toggle between ASCII or Hexadecimal mode display. At the bottom of the display screen you have a list of functions available to move around in the file. Hot Key: AltV Compare Files The Compare Files menu item lets you compare the contents of a file or group of files with the contents of another file or group of files. This function activates the COMP utility. If you need assistance on how this utility works, please refer to the COMP command in Chapter 6. of this manual. Hot Key: AltO Print File(s) 8-8 The Print File(s) menu item sends the contents of one or more ASCII text files to a printer connected to the printer port referenced by the PRN device (normally the LPT1 printer port). Hot Key: AltP Change Attributes The Change Attributes menu item lets you change the file attributes and time and date stamps on an file or range of files. XSHELL will display a screen with the files that have been selected. The cursor will let you change the date and time of the file as well as the attributes - system, hidden, archive, read- only. To toggle each attribute on or off, simply press the space bar. When you have finished, hit [Esc] and XSHELL will then ask you to confirm the changes or not. Hot Key: AltA About X-SHELL Select this item to get information on the X-SHELL version number and the copyright message. Select Group The Select Group menu item lets you select a group of files for further manipulation such as copying, moving, or viewing. You can specify a group of files like *.COM for instance. Hot Key: AltS Unselect Group The Unselect Group menu item lets you unselect a group of files from files which have previously been selected. The files that were tagged previously and that correspond to the unselect filters will be untagged. Hot Key: AltU Gateway to DOS The Gateway to DOS menu item lets you exit XSHELL and access the DOS command line while still keeping XSHELL in memory. Type EXIT at the DOS prompt to return to XSHELL. Hot Key: AltG Exit XSHELL The Exit XSHELL menu item lets you exit XSHELL and return to the DOS command line. XSHELL will keep in its configuration file the setup of XSHELL display for next time. Hot Key: AltX 8-9 The Disk Menu Commands (F3) Add Directory This function is equivalent to the MD or MKDIR function of X-DOS. You must specify a name that does not currently exist in the directory where you are. Delete Directory This function is equivalent to the RD or RMDIR function of X-DOS. Only empty directories can be deleted from the tree. Make sure that when your selection is on the tree you want to delete, no files are available in the file window. Rename Directory This function is equivalent to the RENDIR function of X-DOS. The new name must not exist in the current directory. Change Drive This function allows you to change the drive for the active drive window. You can either click with the mouse on the drive list at the bottom of the SHELL list or by using the left and right arrows move to the desired drive and press ENTER. Format Diskette This function lets you format a diskette from XSHELL. It simply calls the format function with the appropriate floppy drive number. Make bootable diskette This function will transfer the X-DOS system file and Command Processor (as well as its overlay) to a diskette or disk. This function is similar to the SYS function. Copy Diskette This function will activate the DISKCOPY command and copy the source diskette to the destination media. Check Disk This function will call the CHKDSK command of X-DOS which will perform a verification of the integrity of each file and directory on the current drive. Search Disk for text This command is equivalent to the X-DOS find command and will search in the selected drive for a string. It will prompt you for case sensitivity, process sub directories, view files ... Name/Rename Volume This function is equivalent to the LABEL function in X-DOS. Backup/Restore. This command will call the XBACK utility. 8-10 The Utilities Menu Commands (F4) Memory Status This command gives the memory map of X-DOS. It calls the MAPMEM internal command. The memory shown does not include the SHELL memory which is discarded when a command is run. Re-read tree This command reprocesses the tree in case one application created a directory that XSHELL could not detect. If you have created or destroyed a lot of directories either manually at the command line or through other applications, it is a good idea to sometimes re-read the tree to update the SHELL's image of your disk. Security Features The XSHELL security features are divided into two categories: EncryptionXSHELL lets you encrypt files by modifying their content using a password you must specify. XSHELL will encrypt the files that have been selected with the same password. It will prompt you for an extension (by default .PWD) that will replace the extension of the files you wish to encrypt. Remember that the process of encrypting a file does not alter the contents of the original files. You will be requested to type a password up to 20 characters long. Then, one by one, XSHELL will encrypt the selected files and give them their original name plus the extension .PWD or a new extension as specified by the user. If you wish to decrypt files that have been encrypted with the XSHELL utility or the X-DOS ENCODE command, select the file and type in the destination extension (.DCD by default). Type in the original password and after decryption check that the file(s) are OK by viewing the contents. Please note that if you try to decrypt a file that was not encrypted, the destination file will be scrambled garbage. Disk Locking XSHELL also lets you protect your hard disk partitions by locking them so that no unauthorized individuals can pry into their contents when you are not around. You can only lock or unlock partitions if they have been programmed to support locking mode using the FDISK utility. Refer to the explanation of the FDISK utility for more information on this feature. Setup Peripheral XSHELL will call the MODE program and let you change some parameters of your PC. System Time/Date 8-11 This command helps you to change the date and time of the system. 25/43 Line Video If you have an EGA or VGA video card that supports 43 line mode, you can use this command to use the shell in 43 line mode or go back to the normal 25 line mode. Window Switch Like the TAB key, you can change the active window by clicking on this function. The switch is circular. Hot Key : TAB File display format This function toggles the file display format in the directory window from extended display of files (with file size, date ...) to simple display (only file name). In simple display, more file names can be contained in the window. Hot Key : F8 Display filter The display filter enables you to select what files will be displayed in the directory window. By default all files are displayed but you can tune this filter to restrict the number of files displayed. Recall Dos Line By pressing F10 you can also recall the command previously typed in the command line. Hot Key : F10 Directory sort This command will let you sort the directory display according to different filters : name, extension date and size. Undelete file(s) If you have accidentally erased a file or files, you can use the UNDELETE feature to recover these files if they have not been overwritten by another file. You must specify a filespec on entry and XSHELL will call the X-DOS UNDEL command. Format recovery X-DOS offers the possibility to unformat a disk that was previously formatted with the safe switch. This feature calls the format command with the recover switch turned on. File transfer link XSHELL lets you transfer files from one PC to another if both are running XSHELL and connected through the serial port by a Null Modem cable. 8-12 Configuration Each machine must be running at the same of speed in order to communicate. The speed can be adjusted by the change Configuration command and you may select High or Low speed. In case you experience problems using the file link utility at high speed, try using the low speed. The important thing is that both machines are running at the same speed. The communication link can be set to COM1 or COM2 using the standard serial ports. Transmission ProcedureThe machine that contains the files to send is called the master and the machine to receive the data, the slave. When operating the file link function, you should put the slave in receiving mode by activating the Receive File command. A screen indicating that it is waiting for the master to send files will be displayed. If for some reason you wish to abort the procedure, simply hit [Esc]. In order to send files to the slave, you must first select a file or files just as you do when using the COPY function. Having selected the files you wish to transmit, select the function Send Selected Files in the file link menu. The master will first establish the connection with the slave in order to test the speed to be used in the transmission. The file transfer will then be started and a window monitoring which file(s) are being transferred will be displayed. If, having activated the Send Selected Files, the screen display on the master shows the window Attempting Connection with Receiver for longer than 15 seconds there must be some communication problem. In this case the following problems may be the cause: 1.The null modem is incorrectly installed. 2.The serial interface is faulty. 3.The communications ports are incorrectly defined. 4.The speed setting is not the same on both the master and the slave. 5.The high speed setting is selected on both machines, so try the low speed setting. 6.The slave computer is not in waiting mode. Communication Program This item calls X-COM, the built-in full function data communications program. If you have a modem installed in your PC you will be able to use this program to send and receive files over the telephone line. For full details of how to use the X-COM communications program, please refer to Chapter 12. Extension association. XSHELL will only activate files with the extensions .EXE, .COM and .BAT. and will issue an error message if files have a different extension. However, XSHELL has an extended feature that 8-13 allows you to associate files with certain extensions with a command. When you decide to activate a file that is not recognized as a directly executable file (for instance a file with the extension .DOC), XSHELL will check whether this file's extension is associated with a command. If this is the case, XSHELL will activate the command with the selected file as a parameter. Extension associations are user programmable and are saved in a file called XASSOC.EXT. When you activate the extension association command, XSHELL will load the editor internally and let you interactively modify the extension and the command associated with them. If you need assistance on how to use ED, please refer to Chapter 9. in this manual. You can specify one extension association per line, with each line consisting of the following format: [D:][PATH] COMMAND .EXT For example, if you want all the .TXT files to be associated with the X-DOS editor, you would type: ED .TXT or C:\DOS\ED .TXT having made your selection of extension associations, you must save the extension file. In ED simply press [Alt] W or use the Write File function in the main menu to save the file. Then exit the editor and return to XSHELL. Now try running a file with an associated extension by clicking twice on the file name or by typing [Alt] R when the file name is highlighted. You should see XSHELL loading the application you put in the extension application file and updating the program activation parameter with the file name selected. Save configuration. Once you are satisfied with the setting of XSHELL such as the window split, directory display ...etc. you can save that configuration for later. The Applications Function The Application section of XSHELL can be used to collect often accessed programs in groups of similar programs and can record information about each program's type, location on the disk, default associated parameters etc. Those programs, once organized in a small program database can be activated very easily just by clicking on them. You will not even have to remember the name 8-14 given to the binary file corresponding to the program. You could, for example, reference ED.EXE as the X-DOS Editor and then just click on that name to activate it. When you activate the Application section of the SHELL you will see the menu bar at the top of the screen and two main menus. The left hand menu is called the application menu. It will normally contain the program group names you have decided to create. For instance, you could have entries such as Editors, Database, Compilers, DOS Utilities, etc. The menu on the right contains the sub menu referring to each entry in the main application menu. For example, if the first entry you type in the main application menu is Editors, the sub menu will contain a list of the editors you frequently use, such as Wordstar, Xywrite, Brief etc. When the left hand application window is the currently selected window, by moving down the list of application group names you can see the list of programs associated with that group name in the right hand window. The sub menu directory will always carry the name of the main menu. Use the [Tab] key to toggle between the two windows or simply position the mouse pointer in the desired window and click the left button. By clicking on one of the entries or by hitting [Enter] you can activate the utility described by its title without having to remember the actual name of the executable file which you would normally have to type at the command line. The functions of the Applications mode are detailed below. The Menu Bar in the Application Section of XSHELL F1-Help Displays context sensitive help everywhere in XSHELL. F2-Applications Activates a pulldown menu with application functions. F3-Memory Status Displays a detailed map of memory usage. F5-File Management Loads the file management section of XSHELL. The F2-Applications Pulldown Menu The pulldown menu contains the following functions: Add/Edit Menu Item INS Delete Menu Item DEL Reorder Menu Item Alt-R Gateway to DOS Alt-G 8-15 Exit Shell Alt-X Add/Edit Menu Item The Add/Edit Menu Item menu item lets you set up and modify applications in the application menus. Setting Up New Applications: 1. Place the highlight bar on an empty entry in the Application Main Menu. 2. Choose the Add/Edit Menu Item menu item from the F2- Applications pulldown menu. A menu is displayed in which you must specify if you want to create a sub-menu or an application menu item. Note: A sub-menu allows you to set up multiple menu items under a main menu item, grouping related programs under a main heading. An application menu item allows you to directly execute a application program. 3. If you choose to create a sub-menu you are prompted to enter the name for the heading in the Applications Main Menu and you can also specify a password for the user to enter before he/she can access the related sub-menu. When you have done this press the <> key. You are then returned to the applications main screen and a Applications Main Menu menu item is created with the name you specified. If you choose to set up an application program you are prompted with an entry box in which you must specify information which will execute an application program directly. Following is a description of each of the entries in the entry box: Application Title Enter the title of the application you are setting up the way you want it to appear in the menu. Application Directory Enter the directory, including drive, in which the executable file for the application program is located. Application to Run Enter the name of the executable file which will start your application. It is normally a good idea to include the filename extension of the file which starts your program but it is seldom a necessity. Application Parameters Enter any parameters, such as start-up switches, which you may want to pass onto the program every time it executes. Required Password 8-16 If you wish to limit access to the application or the application sub-menu, you can assign a password in this entry. The user will then have to enter the password every time the application is executed. Pause After Execution If you want to make a pause before returning to XSHELL after terminating your application, you should type 'Y' for Yes in this entry. This is useful if your application displays important information on the screen and does not automatically pause itself. Prompt for Parameters If you want to application to prompt for parameters before executing, type 'Y' for Yes in this entry. This is often useful with applications such as word processors which often accept different parameters every time they execute such as a filename. 4. After you have entered the necessary information in the entry box place the highlight bar on top of the last entry, Prompt for Parameters, and press the <> key. The application menu item is set up and you are returned to the Applications main screen. To modify an existing application, follow the procedure below: 1. Place the highlight bar on top of the menu item you want to change. 2. Choose the Add/Edit Menu item menu item from the F2- Applications pulldown menu. If the highlighted menu item is a sub-menu heading, an entry box is displayed in which you can change the name of the sub-menu and the optional password. If the highlighted menu item is an application, an entry box is displayed in which you can change a range of information as described in step 3 under Setting Up New Applications. 3. When you have made the necessary modifications in the displayed entry box press the [Enter] key. Your changes are saved and you are returned to the applications main screen. Delete Menu Item The Delete Menu Item menu item lets you delete menu items from the Applications Main Menu and from the applications sub-menus. 1. Place the highlight bar on top of the menu item you want to delete. 2. Choose the Delete Menu Item menu item from the F2-Applications pulldown menu. 8-17 3. You will be prompted to confirm that you want to delete the highlighted menu item. Select 'Yes' to delete the menu item. You are returned to the applications main screen and the menu item is gone. Reorder Menu Item You may sometimes want to change the order in which the applications and sub-menus are arranged in the Application Main Menu or in any of the sub-menus. You can use this menu item to perform this task. 1. Place the highlight bar on top of the menu item you want to move to another location. 2. Choose the Reorder Menu Item menu item from the F2- Applications pulldown menu. An entry box is displayed in which you must specify the new location for the highlighted menu item. 3. You have to type the quick key letter of the entry to which you want to move the highlighted menu item (a letter from A to O). If the location to which you want to move the highlighted menu item already contains another application or sub-menu entry, the two menu items will change places. Note: You cannot move a menu item to another menu than the one the menu item is currently residing in. 4. When you have typed the quick key letter press the <> key. The highlighted menu item is moved to the location of your specified quick key letter and you are returned to the applications main screen. Gateway to DOS Select this item to temporarily quit XSHELL and return to DOS without removing XSHELL from memory. To go back to XSHELL, type EXIT at the DOS prompt. Exit Shell Select this item to quit the XSHELL program and return to DOS. The F3-Memory Status Menu Item This function shows the remaining memory available to your application not including the Shell which is unloaded when you activate a program. The F5-File Management Menu Item Press F5 to return or go to the File Management section of the shell. 8-18
