( #3333=superdoc: print w/replies, xml ) Need Help??
for what i understood i disagree, there are 3 phases:

clear release the bind of the data to the variable

free the data is released to the mem manager so can be reused by perl

free to OS may happen in some cases after the free.

Where the first 2 are how perl behave, and the last depends on the system (OS + how perl was compiled)

Am i wrong?

    [perldigious]: A question since I'm ignorant of what's normal for database management... Do admins change column names a lot in databases?
    [perldigious]: On occasion my scripts break, because they will do something that seems laregly pointless to me... like in this case, changing a column name from "ABC Category" to "ABC Category Override".
    [perldigious]: Being the ignorant one, my initial reaction to that is, "that's sort of a dick move, a lot of people like me expect column names like that to stay the same, why the hell would you change them like that for seemingly no good reason?"
    [perldigious]: Or is my irritation/ frustration well founded?
    [Corion]: perldigious: That seems to be more the export and likely it's the recipients of that export that like the titles changes
    [Corion]: ... "changed"
    [Corion]: I usually expect fixed header names, but am sometimes lenient in the order of columns. But changing the report titles often sounds to me as if you are not the sole consument of the export ;)
    [shmem]: perldigious: as always - if it ain't broke, don't fix it. Ther must be a very compelling reason for changing column names in a database. Those are rare.
