So I was porting one of my 2002 games to the TI-86 and I ran into some weird issue involving the corruption of random bytes of code in TI-BASIC programs that I run, particularly larger ones (above 5 KB I think). Basically when I launch the program, one character in the code (or more) will be replaced with something else (usually the ►Dec function), so I end up getting random ERR:SYNTAX messages where there shouldn't be and I end up having to resend the programs over and over.

I tested this on ROM 1.3 and 1.6.

Is there an hidden file size limit for TI-86 BASIC programs or is it just a bug caused by how the RAM works on this calculator like that ERR:VERSION bug when ungrouping group files larger than 16384 bytes on the 83+?
