If debug is on, and you are in a try block then either: (a) the try block has a catchd., or (b) you turned debug on in the try block (using 13!:0]1, for example)
And, yes, if the code hits an error, and debug is on, it will suspend there. Also, if the code hits a stop line, and debug is on, it will suspend there. If a line has both a stop and an error, then resuming execution of that line will toggle back and forth between reporting the stop and reporting the error (unless you remedy the error or remove the stop or disable debugging -- if you disable debugging, that would clear the stack). Does this answer your question? Thanks, -- Raul On Wed, Jan 12, 2022 at 3:03 PM Don Guinn <[email protected]> wrote: > > I hadn't but I have now.
