where "n" is an integer from 0 to 31. Only the first 25 define
functions have default values (the values that correspond to the numeric
pad); the Define Functions 26 through 31 are undefined initially. The
following example illustrates how the numeric pad may be reconfigured:
%DEFINE 7=$RUN *PAGEPR SCARDS= PAR=PORTRAIT
%DEFINE 8=$RUN *PAGEPR SCARDS= PAR=LANDSCAPE
%DEFINE 9=$RELEASE *PRINT*
%DEFINE 4=$COPY *PRINT*
%DEFINE 5=$LIST *PRINT*
%DEFINE 6=$DISPLAY RECEIPTS
%DEFINE 1=$DISPLAY *PRINT*
%DEFINE 2=$CONTROL *PRINT* ROUTE=UNYN
%DEFINE 3=$CONTROL *PRINT* ROUTE=NUBS
%DEFINE 0=$MESSAGE RETREIVE NEW HEADER
%DEFINE 20=$EDIT
%DEFINE 21=$SY Q
%DEFINE 22=$DISPLAY TIMESPELLEDOUT
%PAD=DEFINE
This device-command sequence reconfigures the unshifted numeric pad to
insert MTS commands into the input area. The shifted numeric pad is
unchanged and hence may be used for normal numeric calculations. By
placing this device-command sequence into a sigfile, a user may
reconfigure the terminal for every session. The %PAD=NUMERIC command
may be given subsequently to restore the numeric pad for numeric use.
The %DEF? command may be used to display the current definitions of the
define functions.
In PF-key mode, the keys may be redefined to transmit different
characters or sequences of characters to the system. Note that this
differs from define mode where the characters are only entered into the
input area instead of being transmitted directly to the system. Each
key has a program _______ function ________ associated with it. There are 32 program
functions available, labelled PFA0 through PFA15 and PFB0 through PFB15.
By default, the program functions for the numeric pad are organized in
the following format:
┌───────────────────────────────┐ ┌ ┌ ┌ ┌───────────────────────────────┐
┌ ┌ ┌
| PFA13 | PFA14 | PFA15 | | | PFA1 | PFA2 | PFA3 | |
|───────┼───────┼───────| ┌ ┘ | |───────┼───────┼───────| ┌ ┘ |
| PFB0 | PFB1 | PFB2 | PFA0 | | PFA4 | PFA5 | PFA6 | PFA0 |
|───────┼───────┼───────┼───────| ┌ ┘ |───────┼───────┼───────┼───────|
┌ ┘
| PFB3 | PFB4 | PFB5 | | | PFA7 | PFA8 | PFA9 | |
|───────────────┼───────| ┌ ┘ ┘ | |───────────────┼───────| ┌ ┘ ┘ |
| PFB6 | PFB7 | PFB8 | | PFA10 | PFA11 | PFA12 |
└───────────────────────────────┘ ┘ ┘ └───────────────────────────────┘ ┘ ┘
Unshifted Shifted
This particular arrangement of program functions was chosen so that the
numeric pad could be used to simulate the program function pad of an IBM
3278 Display Station when used in visual mode with the MTS file editor
(see MTS Volume 18, The ___________________ MTS File Editor, for further details). Some of
