handling runtime errors

[Jud 1]

Today I pulled out one of my VCL program from a few months ago.  When I ran it, it hit a range check error - giving a message on the screen.  I put the source in the IDS to find the error.  I have R+ and Q+.  When I ran it in the IDE, it gave the same message - it did not take me to the line with the error.  I seem to remember that I did something to handle runtime errors differently, but I can't remember what.

 

What can I do to get the IDE to show me the line where the error occurred again?

 

(BTW, I did find this error fairly quickly with assert statements, but I want the IDE to show me the line with the error.)
