calling to the program basic from assembler

[Fran123]

Hello

I have a BASIC program in &170 address. I want to invoque it from ASM code. How can I do it?

Thank you.

There's no simple way of doing that. Check out the March 89 issue of Amstrad Computer User for the gory details if you must.

From BASIC you had to make a CALL to the ASM code. You just need to come back with a RET.

Hello.
Try with this ...

call &bd19 ;wait v-sync
ld a,2
ld (&b8bF),a ;set scan keyboard two interrupt after v-sync
call &bd19 ;wait v-sync

ld a,255-4
ld (&b645),a     ;pressed R

call &bd19 ;wait v-sync
ld (&b644),a     ;pressed U

call &bd19 ;wait v-sync
ld a,255-64
ld (&b644),a     ;pressed N

call &bd19 ;wait v-sync
ld (&b63F),a     ;pressed ENTER

RET ;return to BASIC
possible GOTO 123
