Thanks for the explanation. I think I understand what you are saying.
In the (on-line) User's Guide, I can't find anything about the use of
a trailing - for options. Where is this documented?
How would one disable just the goto statement, without affecting other
By the way, the User's Guide states that goto statements are disabled
by default. However, the reason we added the -Sg- (attempting to disable
just goto statements) was because after upgrading, suddenly programs
with goto were accepted (and we don't want that in our educational use
of Pascal). Hence, we added the option.
Could it be that the default configuration file also got changed by the
update and now enables goto statements? (This would be confusing.)
