Hi,
I shall put some comments in the assembly, if you don't agree with what I
say, there's an error in the implementation (or a mistake on my side ;)
> I have the following subroutine:
>
> ld hl,(table) ; load table into hl
dynamic start of table: the start address is kept at address table
> inc hl ; increase table
> inc hl ; increase table
2 bytes per entry
> ld a,(hl) ; put value in a
> sla a ; *2
> sla a ; *2
> sla a ; *2
might as well use add a,a. makes it better readable
> dec hl ; decrease table
now you only have 1 byte per entry. either you cut out the second dec hl,
or this is a serious error which will cause data corruption.
> The question is how do I put the value in a back in the table. I
> can't do ld (hl),a. That doesn't work....
As others said, it does. but hl must be pointing right.
I hope you can find the problem. Good luck.
