Yes, it's because you didn't do what I said :) Either install the nightly version of z88dk I linked to, or, add "-DZ88DK=1" to all z80asm command lines.
There was a minor bug in z88dk until I reported it this year, such that the code needs to know if you are building with z88dk vs any other 8085 assembler, and if so, is it below a certain version number. If it's below, then it has to use invalid zilog syntax for RST, but not for any other assembler or for current z88dk either. So the code includes both forms, and Makfile automatically detects the version and tells the code which form to use. But you can't run the Makefile so you either have be using a current fixed version (what I linked to), or you need to manually add the "-DZ88DK=version" flag that tells the code that you have z88dk below the magic version,. "1" is just the simplest way to say "below whatever the magic number is". -- bkw On Mon, Oct 19, 2026, 11:15 AM Georg Käter < [email protected]> wrote: > Thank you for the detailed installation instructions. > > Unfortunately I get the following error, no matter which option I choose > > > TEENY.S85:1031: error: integer range: 3 > > ^---- _RST rst_CompareDEHL ; compare DE(remaining_len) to HL(chunk_len) > > ^---- RST rst_CompareDEHL > > > Any idea how to fix this? > > > > Rgeards > Georg > > > ========== Ihre Nachricht ========================================== > > *von* : Brian K.
