This probably has something to do with line length. BASIC has a 255 char.
buffer for Code lines (whether they have been tokenised yet or not). I'm
wondering if "G.10" gets tokenised to more than 4 bytes, thus causing the
buffer length to be exceeded. "G." [GOTO] will be tokenised as 1 byte, and
the line number (I think, please correct me) is tokenised as 2-bytes,
therefore, I
cannot see why this would cause BASIC to crash.
