-
- VCED (Video Command EDitor) is a ZCPR3 shell which allows you to edit
- command lines that you enter and to recall those that you wish to re-execute.
- Just call it up without any parameters and it will install itself. VCED will
- remain active until the ^_ (Terminate) command is issued from the editor. A
- subset of WordStar commands have been implemented for editing.
-
- VCED is especially useful when typing long command lines, so call up VCED
- before you do several CPs or RENs. A command line such as EDIT FORMAT.MAC;M8
- =FORMAT.MAC;L80 FORMAT,FORMAT/N/E;FORMAT might need to be repeated over and
- over, making it wise to use VCED.

- ^V <-- Calls up the editor.
- ^Q <-- Calls up the editor with help on the screen.

- VCED Notes:
-
- a. VCED starts up in the same way as Z3 usually does: it provides the drive
- letter, user number and the directory name if there is one. Z3 follows
- this information with a '>'. An extra '>' is added so that you can see
- that you are in VCED. The editor will not come up unless you
- specifically request it. To call up the editor, hit ^V. Hitting ^B, ^Q
- or ^O saves a keystroke: They each call up the editor and then perform
- their own functions.
-
- b. Before introducing this version of VCED to your system, erase any
- VCED.VAR that might be present. VCED cannot use VCED.VAR files produced
- by earlier VCED's. VCED uses the ZCPR3 register designated at 111h to
- remember the current location within the circular buffer. So don't mess
- with that register.
-
-
- VCED Notes (continued):
-
- c. Patch points:
-
- 110h
- The size of VCED.VAR is customizable. If you have a 2k minimum
- allocation block, then the buffer size might as well be 2k rather
- than 1k. Number of records - 1, eg: 7 for 1k, 15 for 2k or 31 for 4k.
- 111h
- Register number to use to keep track of current record.
- 112h
- User number for VCED.VAR
- 113h
- FCB for VCED.VAR -- You may change the drive number (A:=1, B:=2, etc.)
- at 113h. The filename may be changed at location 114h.
- 137h
- Name of VCED.COM -- Includes space for DU: and longer name.
- 144h to 14eh
- Punctuation for word right, left.
- command line will be flushed later.
- A byte with an 'F' precedes this flag to identify the alias as one of th
