	KEYS ON VT100
	    FOR
	PORTACALC

	The files KYP.CMD, KYR.CMD and KYSAUX.CMD implement auxiliary
keypad commands when used with PortaCalc for PF1, PF3, and PF4
keys. They need to be inside the login account as presently set up
but can come off DK: device if CMDMUN.FOR is compiled /DEBUG.
	Functions:

PF1 (KYP.CMD)	WIDE - Sets screen into wide mode and sets up display of
		10 columns. (The DB command can vary this)
PF2  (no file)	HELP (gets to top help page. A reply of Hn instead
			of just return will get help page n.
PF3 (KYR.CMD)	NARROW - Sets screen into 80 column mode and sets display
		back to 7 columns (DB command may vary this)
PF4 (KYSAUX.CMD) ENTER - Turns off aux keypad mode and goes into a mode
		of reading input for expressions to enter, entering them
		at current cursor position. The Mn command should have
		previously been used to set automatic motion. Any control
		character or space as 1st entered character, or \ as
		first entered character, gets out of enter mode and back
		to normal command mode.
Note if aux keypad mode isn't turned off, various AKl.CMD files (l varies
from A to N; see cmdmun.for) may be used for user defined commands.


 To implement this scheme rename KYSAUX.CMD to KYS.CMD; otherwise you
use KYS.CMD which means "recalculate" and the keypad is all a lot of
functions.
	Other aux keypad keys are defined as AKm.CMD command files,
where m is a letter corresponding in most cases to the last character
of the generated escape sequence. These are also looked for on DK:
(which on RSX systems is easiest to implement as a single directory
virtual disk (initialize with /SDI switch) globally assigned, or on
VMS is easiest as a system symbol.) This directory should include also
the KEYPAD.PIC file. If AVO option VT100's are used, the file
KEYPADAVO.PIC may be renamed to KEYPAD.PIC in that area, providing a
more legible keypad diagram.
	Most command files will build PortaCalc for the DK: area
since the alternative is to force everyone to have the full set
of keypad command files in his account, plus the diagram. The keypad
may be redefined by editing the files; in that case the KEYPAD.PIC
file should be edited to correspond.
	VT200 escape keys are encoded as KYA.CMD through KZ?.CMD. See
CMDMUN.FOR for the mapping. Basically all keys can be handled, but .CMD
files for all the VT200 keys are not supplied. There's a document in
the aux keypad directory that may clarify this.
