Based on testing, Merlin 16+ labels allow up to 25 characters. should check how EXT/ENT handles long names.

ksherlock commented 4 years ago

REL file allows labels up to $1f (31) bytes long.

ksherlock commented 4 years ago

the label size is very much integrated into the symbol table, so the symbol table and linker need to be updated together. Lots of hard-coded numbers in those files.

ksherlock commented 4 years ago

label size increased to 31.
