Both read exactly the same to me - the case probably takes a bit longer to
digest cos there is more text to read, but there is not much in it. - come

Or perhaps there were more cases in there, and over the years they have been
deleted. The last programmer to have done a deletion probably should have
turned it into an if - but I don't think it really matters, any professional
programmer can figure out what it means in less than a second ;)
Many years ago, MV developers were taught not to use CASE as on the old PICK
machines they evaluated much (much) slower than the equivalent IFs -
probably a bad compiler job. So you ended up with hideous nested IF
statements that became practically unreadable.
My personal preference has always
A little different, but this reminds me of a program I saw once with
nested IFs so deep they actually indented completely off an 80x24 screen
with 3 space indents. I still shudder. The CASE construct was far more
readable.

This is my point exactly. This (and presumably the CONTINUE statement)
is one example where utilizing the semicolon construct is ineffective,
except for comments. Using the FOR/NEXT method is clearly not the
preferred method.

I won't know it's the right string until I perform a few tests on it,

Yeah, it's an interesting adjustment. For those of us who began coding on
things like 8-bit 64Mhz 16Mb boxes, optimizing code was absolutely essential.

$700), 8Gb of RAM 64 bit machine, and it's nearly obsolete. When

I stand corrected!
Edit: it *should be* all the same to the compiler (if the compiler knew what
it was doing)..

Both read exactly
I wouldn't say that's an extra worthless test.
I think what it is telling us is that CASE 1 does not mean otherwise in a
traditional sense.
It really does mean IF @TRUE or IF 1=1
Which is a bit suprising that the compiler would have been written that way,
but it does make a kind of sense.
No one addressed this from the point of actual experience, so I think we can
probably assume that no one has actually scrubbed old back up media.
Just wanted to make sure I wasn't alone in thinking that wasn't a necessary
step.

I've lost contact with Joe Vargas, who when I knew him was living in
Florida and was a member of the Datatel Colleague User Group.
If you know him, could you please pass my email address to him and tell

Thanks.

You are missing my point.
It does mean otherwise to humans.
It doesn't mean otherwise to the compiled code, as we can see.
The compiler does a compare to 1 in order to determine if it should do the
action or jump over it.

or

I prefer:
