Perhaps this was just meant for Bryan(?), but since it made it to the list...

* There is always -set trace on-. This can overwhelm you with output, but can be quite useful when you are trying to see what specifically caused an error

* Within your code, you can put display messages, e.g. -display "Running sub1"-. Or you might set trace on for a specific part of code that is problematic. Or, put in commands like -macro dir-. When I am having trouble, i often find that a piece of code I expected to be executed isn't. Or, that local macros don't have the values I think they should have. You can then figure out from there what the problem is. It may be a simple typo, or it may be a fundamental error in the program's logic.
