KEYPAD.DOC
	PortaCalc will normally place a VT100 terminal into auxiliary
keypad mode. In this mode, all keys except PF2 (which is interpreted
as Help) call indirect files of form nam.cmd in the current UIC. This
permits easy customization. The file names are kyp.cmd,kyr.cmd, and
kys.cmd for PF1, PF3, and PF4, and aka.cmd through akn.cmd for the
other keys. The diagram below lists the names and their locations on
the keypad.
	Note that a number of these files are supplied with PortaCalc
with functions outlined below. The scrolling will move the entire
display left or right; the window left or right only changes cells
down and right starting at the cursor on the display, leaving any
cells above or left of the cursor (which ordinarily would be labels)
alone.
	A bit of added functionality has been added to CMDMUN.FOR to
allow some extra flexibility in command handling. A line beginning in
% is assumed to have several fields:
	%FLD-1%FLD-2%FLD-3
in which FLD-1 if present is typed out to the screen first (used to set
screen widths). Then FLD-2 is passed as the command. If FLD-3 exists and
starts with a ? or \, then the terminal is read and the result is added onto
the end of FLD-2 before the command is passed back to the spread sheet.
If the command begins with a space or control character or a \, then it
is commented out and the command file falls past the % line. If however
FLD-3 started with ? and the initial read-in character is not \ or a
control character, the command file is rewound. This feature is used in
the enter command file (AKD.CMD) to implement an "enter mode" somewhat
akin to that of Visicalc, Supercalc, or others of that ilk by automatically
inserting the "E " of the PortaCalc Enter command until a \ is seen.
If FLD-3 should be present and start with a & character, the auxiliary
file is closed there and console input done as in \ input.
	Note that a file KYSAUX.CMD is supplied which may be used instead
of KYS.CMD. If used, it is the ENTER MODE command and will turn off
auxiliary keypad mode on the terminal. This way, PF4 may be used to
get into enter mode and the numeric keypad used to enter numbers. Recall
that the period (.) of numbers is normally needed for their proper
recognition as numerics.
	Additionally, where the Gold levels are supported (with lines
beginning with "^" incrementing the level), gold-PF2 will be the same
as H9 (help 9), and gold-gold-PF2 will be the same as H10, gold-gold-gold-PF2
will be as H11 and so on. This allows multiple screen picture displays and
makes them more available.

                PortaCalc Auxiliary Keypad Keys
		(Default set of Command Files) (*): ENTER mode if aux file


NOTE:
	The file KEYPADAVO.PIC is an alternate file to KEYPAD.PIC which
may be used for VT100 terminals with Advanced Video Option (AVO) or
equivalents (e.g., DT80). It uses several of the display options to
produce a clearer display. For other terminal types, KEYPAD.PIC should
be used.
	PortaCalc will implement the aux keypad provided that the KY*.CMD
files and the AK*.CMD files are on DK: or the user logged in SY: disk
(depending on whether PortaCalc was built to look on DK:). PortaCalc will
look for KEYPAD.PIC in the same area as the AK* and KY* files as the
keypad diagram. If the supplied KY*.CMD and AK*.CMD files are used, then
either KEYPAD.PIC or KEYPADAVO.PIC should be used and named KEYPAD.PIC
in that area.
