At the moment I don't know where the proble is but the Brady BASIC runs
happily on my IRIX 5.3 system on the old SGI Indigo (it has the R3000
CPU with the "MIPS2" instruction set) but it fail on the O2 with the
IRIX 6.5 (it has the R10000 CPU whic is "MIPS4") on the "RUN" command
every time. It just crashes with the "Bus Error" message. It does not
depend on the compiler used so there must be something wrong in the
code.
