OSBYTE &E1 (225) - Read/Write Interpretation of F-Keys
On entry: A=&E1, <NEW VALUE> = (<OLD VALUE> AND Y) EOR X
On exit: X=<OLD VALUE>, Y=<NEXT OSBYTE> (i.e. current value for OSBYTE &E2)
The values are:
| Value | Function |
|---|---|
| 0 | Ignore key |
| 1 | Expand as normal soft key |
| 2-&FF | Add value to soft key number to provide ASCII code |
On the Electron this controls the effect of FUNC + 0-9.
