Added the ability to go to DOS from the initial screen. Added the ability to display a file's Date, Time, and Size. Hopefully fixed the cursor problem that occurs on mono monitors. Corrected the run command when running programs from a disk that is not in the path. v8.66 -- The video routines have been redone in this release to make them more compatible with a wider range of machines. Directory entries are now presented in the file selection window and can be selected by highlighting the directory and pressing the enter key. v8.65 -- This release corrects a bug when attempting to execute a program file from within an archive file. The documentation has also been completely re-written. v8.64 -- This release adds the capability to supply a password for file encryption/de-enryption. After you choose an ARC file to display press the "G" key. You will be prompted for the password to use. This password remains in effect until you either 1) clear it by press the "G" key again and press the ESC key in reply to the password prompt or 2) by changing the ARC file you are looking at. When you create a new ARC file you will also be prompted to enter the optional password. If you do not want to password protect the ARC file press the ESC key. PLEASE NOTE: If you password protect an ARC file or a member of an ARC file and you forget the password you used to encypt it there is no way to determine what password you used. The password is not saved within the ARC file so be careful. v8.63 -- This release fixes the cursor restore problem when run- ning on a mono monitor. (Please note the "SET MONO=Y" environment variable must be set for this to function correctly). Added in this release is the ability to change the disk and or directory that SHARC is looking at from the first screen. A function key display has been added to the initial screen. The F2 key is now defined as the ChangeDirectory key. Press F2 whenever you want to switch to a different directory. Also added to the initial screen is a line showing the disk, path, and filespec that are currently being displayed. Added the ability to enter a command key when the HELP panel is displayed. For example: you forget what the command key is to freshen a file. Press the F1 key to pop-up the help screen then press the "F" key and the freshen process will be performed. This function was added to aid users when they forget the command key to press for a function. v8.62 -- Adds the ability to add and/or update an archive comment, and/or file comments within the archive file. To add or update the archive comment press CTL-X. To add or update the file comments press CTL-C. v8.61 -- Support for MONO monitors has been put back in. To use SHARC on a mono monitor set the environment variable "MONO=Y" (i.e. SET MONO=Y). Using this environment variable will override any color definitions that were setup using the SHARCFG program. v8.60 -- Implements a configuration file for SHARC and drops the SHARCL.EXE version of the program. SHARC will run with- out its configuration file but then you must live with my default values. The items you can change via the configuration file are the screen colors, the arc and de-arc program names, the disk drive to use as a work drive, and the amount of storage to reserve for differ- ent buffer space. To build the configuration file exe- cute the program SHARCFG. The program will prompt you for all necessary information. It will then build a file called SHARC.CFG on the default disk and directory. You must then move the CFG file to a directory that is defined in your path. The SHARCL.EXE program was dropped since a user can now configure SHARC to allocate its buffer space via user specifications. The default arching program is PKARC.EXE, de-arching program is PKXARC.EXE, number of files per ARC file 500, number of files per directory = 500, work disk = current default disk. For those users that have experienced problems looking at ARC file on a floppy that is full. Use the SHARCFG program and set the work disk drive to either your other floppy drive, or your hard disk drive. Then when SHARC instructs the de-arc program to unpack the file for viewing it will unpack it on the defined work drive instead of the floppy drive. v8.52 -- This release includes the program SHARCL.EXE. This program is a large data model of the SHARC program. It will handle up to 500 ARC files in a single directory, 500 non ARC files, and 1100 files within an ARC file. It is a little slower than the regular SHARC program but some users needed support for a great number of ARC files. In addition the ARC scanning routines have been re-written and are about 15% faster. Also on the fill list window that appear on the left side of the screen a small box will appear on the right hand side of the window. It will show you the relative position of the highlighted file in the file list. v8.51 -- An enhancement has been added in this release that posi- tions the file list display pointer to the last file selected. The list is still scrollable and pagable, SHARC just remembers the last ARC file you selected from the list and positions the pointer to that file for you the next time the file list is displayed. v8.50 -- Adds a speed search facility to both the file list pop- up window and the ARC file list. To use the speed search facility in the pop-up window simply press the first letter of the file name you want to scroll to. The list will be repositioned to the file that starts with that letter or the closest thing to it. To use the speed search facility within an ARC display press ALT-S and then press the first letter of the file name you want to find then press enter. v8.40 -- Fixed a minor bug in the command line parsing routine. v8.30 -- Supports ARC's with up to 1098 files in an ARC file. A new option has been added to display ARC and file com- ments within the ARC file. To use this option press ALT-I. The implementation of this option is not very elegant but it works. v8.20 -- Supports updating an ARC file using the ALT-A, ALT-F, ALT-M and ALT-U commands, when the files are in a dif- ferent directory than the ARC file. PLEASE NOTE THAT THESE COMMANDS REQUIRE PKARC v3.6. The "S" command has been added. It allows you to switch to other ARC files in directories other than the one specified on the command line. The "C" command has been added. It allow you to create a new ARC file. When specifying the new ARC file you can enter the disk and directory you want the ARC file to reside in. THIS COMMAND ALSO REQUIRES PKARC v3.6. I have also included a registration form file with this release. If you have been using SHARC please register!! v8.00 -- This release address numerous comments from users of SHARC over the past few month. The program has been corrected so that the cursor is restored when SHARC is finished executing. The file list is now sorted and can be scrolled up and down in addition to being able to page up and down. Four new commands have been added. They all prompt for a filespec which can include drive and path information. A file list is then presented based on the entered file specification. When the file list is on the screen use the SPACE bar to toggle the tagged status of the file (IF a file is tagged the "»" character will appear to the left of the displayed file). When you have tagged all the files that you want included in the operation (ADD, FRESHEN, MOVE, UPDATE) press the ENTER key and all tagged files will be acted upon. The four new command keys are: "ALT-A" to add a list of files to the current ARC file; "ALT-F" to freshen a list of files to the current ARC file; "ALT-M" to move a list of files into the current ARC file; "ALT-U" to update a list of files in the current ARC file. If you start SHARC by specifying wild cards on the com- mand line pressing the ESC key will return you to the file list presented when SHARC was first started. To exit SHARC press the ESC key again. v7.00 -- Adds the ability to execute an EXE or COM file from within the ARC file. The EXE or COM file is extracted into the current drive:\directory then you are prompted to enter any command line options. The program is exe- cuted and then deleted. v6.30 -- Fixes a problem that occurs when tagging files for ex- taction. Under the prior release, if you tagged the last entry in the ARC file for extraction it would not be extracted. It's now fixed. v6.20 -- Fixes a bug when SHARC is started and you specify a file on the command line. Prior to this release if you speci- fied a file on the command line, then used the "N" com- mand, SHARC would terminate. Now, you will be presented with a list of all files in the current directory that have the ARC extension. v6.10 -- Added the "M" move option. This option will allow you to specify which files to move into the currently select- ed archive file. If the files are successfully moved, they will be deleted. Also if SHARC detects an error from PKARC or PKXARC (or PKPAK/PKUNPAK) a message will be displayed on the screen and the screen will not be cleared until a key is pressed. v6.00 -- Please note that there was no v5.x. Additional support for PKARC v3.6. You can now TAG files for extraction by pressing the space bar to toggle the TAG status. Then press the CTRL-E key to extract all tagged files. For those of you that have monochrome monitors and can't see the selection bar try setting the environment variable "mono=y" (i.e. "SET MONO=Y"). I think this should solve the problem. v4.10 -- Adds support for release 3.6 of PKARC and PKXARC. SHARC will automatically determine which version is on your machine and will use whichever version it finds. v4.00 -- Support for monochrome monitors has been added. SHARC automatically senses a monochrome monitor and adjusts the screen attributes for the monitor. Two small "bugs" have been corrected. When an extract path is entered it stays in effect for the entire ses- sion or until you change it. The window scrolling rou- tine was corrected to correctly handle the end and cursor down keys after selecting a file for extraction or view- ing. v3.00 -- A file list window has been added in release 3.0. This window replaces the "N" command and ALT-N command. When you specify wildcards on the command line, a filelist window will appear. Use the cursor keys to highlight the file you want to work with and press the enter key. After the contents of the ARC file are displayed you can POP-UP the file list window again by simply pressing the "N" key.
