Re: High level record lock

I need to replace the SQL logic with good old-fashioned:
CHAIN (locking the record)

This is perhaps the single most compelling argument for keeping RLA
around. Hard to beat the elegance and simplicity of this
record-locking mechanism.

And incidentally, it's one reason why iSeriesPython is such a special
language. It's not *just* Python (which I think is awesome already).
It's Python implemented in ILE, with full RLA capabilities in addition
to the SQL that every language under the sun has.

I haven't fully investigated IBM's Pythons for PASE yet, but I am
fairly doubtful that they can make use of RLA so easily. (I know you
could write a "helper" in RPG, and then call *that* from Python, but
of course that's not as easy or seamless as what I'm looking for.)
