The info(“errorstack”) function returns the contents of the procedure stack after an error.

Description

This function returns the contents of the procedure stack at the time the last error occurred. See info(“procedurestack”) to learn more about this stack. See Error Handling to learn more about how to trap an error with the if error, try/catch or onerror statements.
