7 ;;; The VShell maintains a Command Line History (CLH) that allows you to
8 ;;; capture, edit, and reissue up to 20 commands. Actually there are 4 separate
9 ;;; CLH's, one for each module of VPE (VGL,VRR,VEDD) and one for the VShell itself.
10 ;;; Hitting the left arrow key will display your last 20 commands, and allow you
11 ;;; to edit and reissue any one. You can use the up and down arrow keys to move
12 ;;; up and down the CLH, and edit and reissue any individual command.
13 ;;;
14 ;;; If you have a previous command that you wish to convert to a User QWIK, move
15 ;;; to that command using the arrow keys, and then hit <ESC>Q for the QWIK
16 ;;; dialogue. The QWIK you create will use the code from the CLH.
17 ;;;
18 ;;; You may purge the CLH at any time using the following System QWIKs:
19 ;;; ..PURVSHL Purge VShell CLH
20 ;;; ..PURVRR Purge Routine Lister/Editor CLH
21 ;;; ..PURVGL Purge Global Lister/Editor CLH
22 ;;; ..PURVEDD Purge VEDD CLH
23 ;;;
24 ;;; As commands are added and dropped from the CLH, the number of any individual
25 ;;; command can become large. Each time you enter the VShell the CLH is renumbered
26 ;;; back to 1-20. You can manually renumber the CLH with System QWIK ..CLH.
27 ;;;
28 ;;; If you have the ^%ZOSF("UCI") global node on your system, VShell will delete
29 ;;; the SHL Command Line History whenever you switch UCIs. This is to protect you
30 ;;; from accidientily rerunning a command in the wrong UCI.
31 ;;;
32 ;;; The CLH is an extremely useful tool and you should become proficient in its
33 ;;; use. Remember, it is also available in VRR, VGL, and VEDD.

38 ;;; The VShell includes a number of programmer tools that range from a single
39 ;;; routine to very sophisticated packages. They all have one thing in common:
40 ;;; They're useful. These tools are System QWIKs and are located in Box 3. Type
41 ;;; '..3' to see them. To use them, type two dots and the name.
42 ;;;
43 ;;; E A routine editor that uses the VRR module.
44 ;;; ASCII Displays the ASCII character set.
45 ;;; CAL Six month calendar display.
46 ;;; KEY Display escape sequence for any key struck.
47 ;;; VEDD VElectronic Data Dictionary - An easy to use utility for viewing the
48 ;;; structure of Fileman files.
49 ;;; VGL VGlobal Lister/Editor - A tool to examine and edit globals.
50 ;;; VRR VRoutine Reader - Used to read routines. Allows branching to up
51 ;;; to 4 routines so you can follow any branching logic contained in the
52 ;;; code.
