Hi Bob, thanks. That's a good succinct summary.

I like my BEGIN blocks because they represent "logical groupings" of my
logic. I could shift one way and replace them with PROCs, or I could
shift the other way and place the BEGIN block code inline with the code
that contains it (and remove the BEGIN).

Of these three options, I chose BEGIN. When I leave the BEGIN block
everything is wrapped up automatically and I have a "fresh start" for
the following section of code without having to check backwards to see
what was allocated and must be deallocated. And as for PROCs, they have
a bit more overhead and, frankly, I think they're unsightly when they
appear in the middle of other code (I like to keep stuff straight-line
so I can easily understand it later).
