Hello,

I accidentally posted this in the open discussion forum, I'm not sure how to delete it but I will just re post this here with more info…

I am currently writing a op code test file for an open core z80 processor, but I am having some problem compiling my code using the sdcc. For example, testing ADD A, (IX + 5) I receive an error "missing or improper operators, terminators or delimiters". I have also tried ADD A, (IX + 5H) ADD A, (IX + 0x05) ADD A, (IX + #0x05) and a couple of other variation but have had no luck. Does anybody know how to perform this action? I assume I just have the syntax wrong.

This is my make file:
sdcc %1.c -mz80 -code-loc 0x0000 -xram-loc 0x8000 -no-std-crt0
packihx %1.ihx > %1.hex

SDCC version 3.2.0 (also tried this with 3.1.0)

Code snippet:
LD A, #0x11
LD IX, #0x8000
LD HL, #0x8005
LD (HL), #0x22
ADD A, (IX + 5)

Interestingly enough, it does compile without error ADD A, (IX) with the correct opcode (DD 86 00)
I experience the same problem with all operation involve IX+d or IY+d

Any help would be greatly appreciated :)

ok so apparently the compiler was looking for

ADD A, 5(IX)

problem solved.
