hello, day.
I have 3 inline ASM that work.
In bank 1, bank 2, bank 3 the inline ASM is loaded from address Sa000.
this 3 inline is ok.

poke 0,3
sys $a000 is ok

These no longer work after the first call. no reaction.
poke 0,1
sys $a000 not ok

poke 0,2
sys $a000 not ok.

-------------------------------
POKE 0,1
RESTORE MATH
READ Z
FOR P = 0 TO Z-1
READ A
POKE $a000+P,A
NEXT

POKE 0,2
RESTORE SCHLEIFE
READ Z
FOR P = 0 TO Z-1
READ A
POKE $a000+P,A
NEXT

POKE 0,3
RESTORE SCHLEIFE1
READ Z
FOR P = 0 TO Z-1
READ A
POKE $a000+P,A

this is ok with : sys $a000 , sys $a000+100 , sys $a000+200

then poke 0,6
poke $a000,123

poke 0,1
sys $a000 , sys $a000+100 , sys $a000+200 not ok.

Do not POKE 0 or POKE 1 in BASIC. Use the BANK command.

BASIC switches banks for its own purposes, so you have to use BANK to select the bank that gets used for POKE, PEEK, SYS, USR, and WAIT. (I think that's all... but someone will tell me if I missed one.)

thanks for the tip.

now works great with the inline asm in basic.

Great! =)

This is why I love 8-bit computers... you don't get to do this kind of hardware-level stuff on a PC.
