In the F-specs, define a display file with a continuation line for the buffer to hold the device description:
FDEFAULT#CF E WORKSTN
F KINFDS DEVICE
In the I-specs, add the following:
IDEVICE DS
I 1 8 ##SCRN
I 38 45 ##RECF
I 369 369 ##KEY
I B 370 3710##CURS
then, right before your the C-specs begin, add the following code:
I DS 31
I 1 1 ENTER
I 2 2 ROLLUP
I 3 3 ROLLDN
I 4 4 HELP
I 5 5 PRINT
I 6 6 BSPACE
I 7 7 CLEAR
I 8 8 F1
I 9 9 F2
I 10 10 F3
I 11 11 F4
I 12 12 F5
I 13 13 F6
I 14 14 F7
I 15 15 F8
I 16 16 F9
I 17 17 F10
I 18 18 F11
I 19 19 F12
I 20 20 F13
I 21 21 F14
I 22 22 F15
I 23 23 F16
I 24 24 F17
I 25 25 F18
I 26 26 F19
I 27 27 F20
I 28 28 F21
I 29 29 F22
I 30 30 F23
I 31 31 F24
