Hi, it is a working Z8000 system with a ZEUS clone (SYSIII UNIX). Somehow the assembler must be able to put the segment information for the absolute adress of this array in the object. No idea how tho, as $abs will only work on segment 1. I have the original .o file from Zilog and there is the fi

Putting things at an absolute address requires putting things into segments that are handle by the linker or loader (depending on what era you are working in). the linker may place the output of your assembler into different segments. They may be set up to be relocatable at run time (most OSs

Hi, I found out so far, that %3e00 means, that the data is put on segment 62 (0x3e). Regarding to the Z8000 ASM handbook, segmented adresses are notated as <>offset, so in my case <<62>>%F600 - but of course it does not work and the assembler yields and error :( Oliver Lehmann wrote: Hi,
