- Getting Numeric Input
- ==============================================================
- by Linus Akesson
-
- This is done in about the same way. Start by putting the
- prompt at 821ch:
-
- ld de,821ch ;put the prompt here
- ld hl,prompt
- ld bc,prompt_len ;length of prompt, max = 16
- ldir
-
- Then call PGMIO_EXEC, but with a different command in ASM_IND_CALL:
-
- ld a,1 ;code for NUMERIC input
- ld (ASM_IND_CALL),a
-
- call PGMIO_EXEC
-
- The input is automatically parsed as an expression, and the result is placed
- in OP1.
-
- call _formDisp ;display it
- ret
-
- prompt: .db "Inp:",0
- prompt_len = $-prompt
