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.
