You could 'delete' or 'undef' variables you don't want. But I sense that
you want a bigger wiper than that...
If you define variables using 'my' in the sub, Perl's gargbage collection
should annihilate them when it has time/needs resources. It might even
eliminate them as soon as you exit the sub.
eg
...lotso code ...
my $var1 = "wowzers";
my $result = testSub();
## at this point $var1 and $result should have values. $foo and $bar won't.
## Unless you have other $foo and $bar variables declared at this ## scope
level!
## If you are looping through testSub, each iteration will overwrite (or
replace) $foo
## and $bar, so you shouldn't have 'phantom' variables taking up any space.
## if you wanna force a variable to dissappear, undef it. Again I am not
## sure when the garbage collection reclaims the unused memory. I am
## assuming that it will do it immediately, but I could be wrong (and often
am! ;-).
undef $var1;
sub testSub
{
my( $foo, $bar ) = ("bah", "humbug");
[ do stuff with $foo and $bar ]
}
## WARNING - sluping a large file into a variable will eat up copious
amounts
## of memory! My win2k and NT boxes unceremoniously exits Perl with an
error when a
## single Perl instance occupies > 82MB! So code to avoid this horrible
'feature'.
<rant>you'd think that a server with 512MB of *unused* RAM would be able to
have a Perl instance of up to that free space. But nooooo.</rant>
