Ok, got some spare time to spend on ASM, so I tried to read a catalog from disc ... so BEWARE OF NOOB QUESTIONS IN THE FUTURE :laugh:

entry point is an adress in DE

so all I tried so far is :

Code Select


org &2000
ld de,(&4000)
call &BC9B
ret

But this only prints the catalog to the screen, mem location &4000 is still empty (well I know about "vdu txt disable" but shouldn't it write the catalog to &4000 also ?) ...

Shouldn't that be LD DE,&4000 ?
