I have an old script where they have a "Main:" in it
in the following syntax:

Main:
{
    ###code in here...

}

I've never come across this before, are there any security concerns here?
and why would someone do this?

Hope you New Year is bright!

Joe McTigue

Hi from a chilly Vienna. Thankfully, the airport is warm inside and I'm only here for a few hours anyway - getting a connection and heading for the Perl Workshop in Israel, which is pretty exciting!

Took me a moment to realize what it was! Anything followed by a colon is just a label. When you attach a label to a block, you can do things like:

last LABEL;
next LABEL;

And so on. So if you have nested loops you can state which one your control "exceptions" apply to. So look for usages of the Main label in the code, to see why it's there. If it's unused, I'd guess it's redundant.

Thanks, same to you!

Thankfully, I'm now in Tel Aviv, which has been nice and warm today.

Jonathan, quick question... Different topic...

In using DBI, can you send PL/SQL or statements using cursors
in your prepare statements and execute them successfully?

All the Best,
