- OVERVIEW
-
-
-
- This document provides information about CAT for use on the IBM
- Personal Computer. We hope the program fills as many of your
- needs as it did ours. After all, that is the reason we have
- developed this integrated package. The better tools you have to
- work with the better the end result.
-
- It provides a full screen list of a file set specified by the
- user. These may be presented in an unsorted, name, extension,
- date, or size order, and the sorted order of presentation may be
- changed dynamically. Within each entry is displayed an area to
- allow the entry of commands. This command area may be used to
- issue commands which pertain to the files displayed. These
- commands are entered in the command areas adjacent to the files
- they are to affect. Helpful facilities are provided to lessen
- the typing required. One example is the use of the "=" internal
- command to repeat the last command. To provide additional ease
- of use, the editing keys and function keys may be used to page
- through the list and add or delete commands.
-
- When all desired commands have been entered, the user enters exec
- execution mode to pass the commands entered in display mode to
- the PCDOS command environment. The commands are passed to the
- command environment for execution one after the other, befinning
- with the command closest to the top of the list and continuing
- toward the end of the list until all commands have been returned
- or an internal function is encountered. If no internal command
- is encountered, the DOS prompt appears, with a full block cursor.
- Entry of a null command (i.e. return) will redisplay the the
- file list. Any other entry will be immediately executed by DOS.
- The DOS prompt is displayed to allow you to view any messages
- which were put on the display by the executed commands.
-
- The program becomes a resident extension of DOS in core. It
- occupies approximately 7k bytes of stroage. This storage
- includes the necessary resident code and table space for an
- unlimited amount of entries. Cat will remain active in core until
- the system is rebooted.
- BACKGROUND:
- CAT is invoked from the DOS command environment by issuing the
- command: A>cat (refer to figure 1)

-
- If the filespec is omitted, all files on the current default disk
- will be listed. If CAT is used on the IBM PC/XT only those files
- within the current directory are listed. If you specify /sn then
- the files will be listed in alphabetical order of the filename.
- If you specify /se then the files will be listed in alphabetical
- order of the filename extension. If you specify /sd then the
- files will be listed in date sequence. The very first will be
- the most recent entry and the last file in the listing will be
- the oldest file entered. If you specify /ss the files will be
- listed by size. The largest file first contiuning to the
- smallest file.

- SCREEN FORMAT:
- The displayed format consists fo three distinct areas. The first
- line is a status line. The dirst two characters are the DOS
- prompt currently active. The balance of the line gives the size
- of the allocation unit, the allocation units used and the
- allocation units free (as well as the percentage of free
- allocation units) on the listed diskette plus the number of the
- first displayed entry as well as the count of active (displayed)
- entries.
-
- The next 23 lines contain displayed entries for listed files.
- The first portion gives the filespec for the listed file. The
- next 25 postions are a command area. The balance of the line
- contains the attribute indicators, the size of the file in
- decimal bytes, the number of allocation units occupied by the
- file, followed by the date and time the file was last updated.
-
- The last line of the screen displays the function key settings.

-
- Manipulating the display.
-
- Once the list is displayed, the editing keys on the keyboard may
- be used to manipulate the screen. The semantics for the key
- useage follow those used for the BASIC editor. They are:
-
-
- PgUp move the display to show entries nearer the beginning of
- the entry sequence.
-
- Ctrl-PgUp move the display to show the first screen of entries
- in the entry sequence.
-
- PgDn move the display to show entries nearer the end of the
- entry sequence.
-
- Ctrl-PgDn move the display to show the last screen of entries
- in the entry sequence.
-
- Home position the cursor to the first postion of the command
- area on the first entry displayed on the screen.
-
- End position the cursor at the last character in the command
- field on the line containing the cursor.
-
- Ctrl-End erase the command area from the cursor to the end of the
- field.
-
-
-
- Ins toggle insert mode. When in insert mode, a full block
- cursor is displayed.
-
- Del delete the character at the cursor.
-
- Cursor keys move the cursor in the directions depicted by the
- arrows. If the cursor movement is up or down and the
- movement would result in moving onto the first or last
- line of the screen and thefile is not already positioned
- with the first or last entry on the top or bottom line,
- the screen will be scrolle up or down.
-
- Enter positions the cursor to the beginning of the next
- command area. If appropriate, the screen will be scroll-
- ed as described below in the entry for Tab.
-
- backspace deletes the character to the left of the cursor.
-
- Tab skips to the first position of the next command area
- unless the skip is off the last entry displayed. In this
- case, scrolling occurs as for down cursor unless pro-
- hibited by file position. In this case, wrap to first
- displayed command area occurs.
-
-

-
- Shift-Tab skips backward to the beginning of the previous command
- field. If the cursor is not in the first position of
- the command area, this key will position to the first
- position of the current command area. If the skip is
- off the first entry displayed, scrolling occurs as for
- up cursor unless prohibited by file position. In this
- case, wrap to last displayed command area occurs.
-
-
-
- ESC clear the command area to blanks then position the cursor
- to the first position of the command area on the current
- entry.
-
- Ctrl-Return enter the execution mode.
- [CR]
-
-
- While in execution mode a block cursor will be displayed along
- with the DOS prompt, CAT remains active in core and can be
- recalled simply be depressing [CR]. CAT will display the
- previous entries from your previous session. Simply depress [F1]
- to refresh and update the current display.
-
- Program Function Keys
-
-
- The functions provided on the PF keys are displayed on the 25th
- line of the display. The assignment is similar to the BASIC
- softkeys, with the function key placing the assigned character
- string on the command line at the first position, then entering
- execution mode. The function key assignments are as following:
-
- [F1] SUBMIT-update display with all entries in current directory.
- [F2] XCLUDE-exclude entry where cursor is positioned until the
- display is re-SUBMIT-ed.
- [F3] READ=C-read and display entries from drive C: in current dir
- [F4] READ=A-read and display entries form the floppy diskette.
- [F5] SRTNAM-sort(ascending) on name and update display.
- [F6] SRTEXT-sort(ascending) on extension and update display.
- [F7] SRTDTE-sort on date(most recent displayed first) and update.
- [F8] SRTSIZ-sort on size(largest displayed first) and update.
- [F9] EDIT -executes IBM professional editor.*
- [F0] SCAN -executes SCAN.COM(allows you to browse your text or
- programs, no changes allowed just checking activity)
- Once in SCAN you may end the session by depressing
- the [ESC].

-
- *-Send us your copy of CAT along with a check for $10.00 to cover
- postage and handling and we will change the PF key setting to
- execute your preferred editor.e.g.-WS(wordstar),VW(volkswriter)
- EDLIN(editor on DOS diskette) or your personal preference. Make
- sure to include a note stating your requirements.
-
- Using the Command area:
-
- The input areas after the fileids may be used to enter any
- command as in the normal DOS environment. If not otherwise
- directed, CAT will append the complete filespec associated with
- the command area at the end of the command line. If the command
- is preceded by the /O internal command, no appending will occur
- and the command will be passed to the command environment without
- further processing. The /n internal command will allow you to
- execute the current filespec. As noted earlier the "=" will
- allow you to repeat your command without having to retype it. To
- copy a particular file to the A:drive use the following format
- on the command line: COPY / A:-this will copy the file to drive
- A. The "/" causes cat to insert the filespec located on the same
- line as you are entering the command. If you need to sort on
- particular filenames then enter the following: /r *.mem
-
- Then press the [Ctrl] and [CR]. The block cursor will show along
- with the DOS prompt, just press [CR] for your requested list.
-
- Additional commands which may prove to be very valuable are HIDE,
- EXPOSE and PROTECT. Type the command HIDE on the line of a
- filespec you wish to conceal from prying eyes. Then depress
- [Ctrl]-[CR] to hide the file from most normal directory searches.
- Press [CR] to return to the CAT display and press [F1] to update
- the display. You will notice the capital H displayed on line of
- the filespec you specified to hide. Use the command EXPOSE to
- reveal the hidden file. PROTECT will protect a file from
- accidental erasure. Use the EXPOSE command to authorize erasure.

- IF YOU ARE USING THIS PROGRAM AND FIND IT OF VALUE, YOUR
- CONTRIBUTION ($35 SUGGESTED) WILL BE APPRECIATED !
