TOPIC:

I used to get the line number where a compilation error occurred shown in Messages window.

Now all I get is "Compile Project, Target: CardScroller(v2).exe: Exit code 1, Errors: 1"

Is there an option I need to turn on?

Yes Sir
Typhon IDE => Project Options => Debugging page

I would have guessed that this was for debugging rather than compilation, but yes, I have this set, but still get no indication where an error is in the source. For example, when I use a variable named ccounter when it has not been declared, I still only get "Compile Project, Target: CardScroller(v2).exe: Exit code 1, Errors: 1
Fatal: Compilation aborted"
Also I have Typhon IDE => Project Options => Verbosity page => Show line numbers (-vl) checked.
