OSBYTE &E1 (225): Character &80-&8F interpretation
OSBYTEs 221 to 228 control the interpretation of characters &80-&FF when read from the keyboard buffer, or the serial input buffer when character interpretation is enabled.
| OSBYTE | Characters | Modifier | Keys | Default | Effect | Electron notes |
|---|---|---|---|---|---|---|
| OSBYTE 225 | &80-&8F | - | function keys 0-9, cursor keys | &01 | soft key | default=&01, FUNC+numbers, cursor keys |
| OSBYTE 226 | &90-&9F | SHIFT | function keys 0-9, cursor keys | &80 | &80-&8F | default=&01, FUNC+A - FUNC+P |
| OSBYTE 227 | &A0-&AF | CTRL | function keys 0-9, cursor keys | &90 | &90-&9F | default=&01, FUNC+Q - FUNC+Z, FUNC with : ; , - . / |
| OSBYTE 228 | &B0-&BF | SHIFT+CTRL | function keys 0-9, cursor keys | &00 | ignore | |
| OSBYTE 221 | &C0-&CF | - | function keys 10,11,12, Insert | &01 | soft key | |
| OSBYTE 222 | &D0-&DF | SHIFT | function keys 10,11,12, Insert | &D0 | &D0-&DF | |
| OSBYTE 223 | &E0-&EF | CTRL | function keys 10,11,12, Insert | &E0 | &E0-&EF | |
| OSBYTE 224 | &F0-&FF | SHIFT+CTRL | function keys 10,11,12, Insert | &F0 | &F0-&FF |
Break inserts &CA into the keyboard buffer. On some systems, Alt+key is treated as a SHIFT+CTRL modifer. Note that SHIFT+CTRL also has the function of pausing screen scrolling, so entering SHIFT+CTRL+key interactively may pause scrolling.
The interpretation values are:
- 0 - ignore the character
- 1 - expand as soft key or Electron shortcut key for &90-&AF
- 2 - return &00,character (MOS 3.50, MOS 5 and later)
- otherwise, use as a base value and add to (character AND 15)
