I suspect the problem is with the tokenisation routine.  In almost all
cases the tokenised version will be shorter than the original, but I
suspect that G.10 actually expands to perhaps something at least as long
and perhaps longer than the original.
If I remember correctly the line number was stored in an odd way (was it a
3 character???).

If that is the case then perhaps the tokenised line actually comes out as
too big and the poor thing gets confused.  If you used GOTO 10 of course
you will have had less tokens.

(The emulators should have no problem recreating the behaviour becuase
they are emulating at the register level!).
