Hi Nick,

Thought I would start a new thread.

>>>I just used RETRY recently in VFP 8 app. :) There I need to make a certain number of retries to open the file that can be under another process at the moment, and cannot yet be opened. I used a combination of ON ERROR and TRY/CATCH.

But with ON ERROR the code that contains your RETRY will be in a function altogether different from the function you're writing. You're decoupling all of the exception code from your function code which only makes following the program more difficult, a cost with no thinkable benefits.

As an excersize in understanding exception handling, perhaps you wouldn't mind posting your code with RETRY? We'll adapt it to try/catch for analysis?
