Robert,

Under QBasic 'end' terminates the program.  Are you sure you didn't mean 
'end if' there ?

(That all the files are closed could easily be part of PDS'es clean-up 
activities before actually terminating)

As you have not posted the involved code and I (we) do not have any kind of 
mind-reading capabilities there is nothing I (we) can say about that.

It certainly enables you to write goto-enabled spagetti code (as in: 
unreadable/trackable code).   Why do you think most languages dropped the 
'goto' and/or strongly advice you NOT to use it ?  :-)


Basic bug-hunting most often boils down to isolating the problem by removing 
everything that does /not/ make the problem disappear (and sometimes 
replacing variable and/or human input by fixed stuff).   If you're lucky 
you're left with a single line. :-)
