water,
Being what I would refer to as a "migrator scripter", it would appear that i do make assumption, and, as a result, the "a##" in me has been, shall we say, "exposed".
This being said, my overall scripting requirements are rather simple ones. Thus, the need for "error checking" has never, ever been an issues. This "non-issue mentality" however, is now being altered - observing the need for such "coding practices".
The provided link regarding "Functions" has been a real "eye opener" ...so I just want to extend a heart-felt sense of gratitude to you for for that suggestion.
