Diego,
That's not a bug... In (at least the coco) basic, the "for-next" 
variable  contains +1 at the end of the loop.
Try this:
10 FOR A=1 to 10: NEXT
20 PRINT A

This should print 11.

In your case, if I understand correctly, you're executing a subroutine 
if A$=B$, then you're starting the FOR loop again after that, right?
If that's what you wanted, in line 1070, A would be set to 73, because 
the condition A$=B$ was false for the 72 tries...
