Although gen_reloc looks like it was originally tightly tied to TASM's symfile format, the default Makefile doesn't even pass the symfile to gen_reloc. It appears that the version of gen_reloc released with HTERM uses only the binary object files with ORG=0 and ORG=1, which my Makefile does create. That implies to me gen_reloc should work with any assembler. It certainly goes through the motions when I run it: gen_reloc creates a .DO file that looks vaguely right (using %-escapes to mark addresses to be relocated), but once it has poked everything into RAM, calling SYS just gives a "?SN Error". (For reference, the .CO file that gets compiled runs fine on my T200.) Since you don't recall it being broken, I'm going to presume I'm doing something wrong. But you may not need a relocating loader, you may be better off working > around it. Both are likely true. But I've become more interested in relocating loaders since that's one of the things my co2do script doesn't yet handle — except internally for its own M/L decoder in a string. (Currently, it relies on parsing the .LST file from asmx which seems too fragile.) It also seems like a relocating loader might be the only way I can have a single program larger than 2.4K that can run on any of the Kyotronic sisters. —b9
