I keep all my import variables in a hash for safe keeping. I let these dynamic variables as listed above exist in the main root hash environment (if you could call it that).

so there's %ENV, %GET, %POST, %IP, %DEFAULTS, and %DATABASE. This is safer anyway. measure twice, declare once. I'm still not saying i'm right, but anti-soft reference arguments don't float.
Maybe it's the hash.

I wonder if a reminder of the beauty of 'local' would also help the case here.

After reading dominus's arguments against soft references i still remain. One could spend hours telling you how dangerous using perl is when you use the shebang line.

Then, i thought of 'local' and did a test...
Error 500 in the face.

This doesn't work.

#!/usr/bin/perl
&tryLocal("name=james&color=red&age=12");
exit;
####################
sub tryLocal{
local $in = $_[0];
@in = split(/\&/,$in);
foreach $li(@in){
($lname,$lvalue)=split(/\=/,$li);
local $$lname = $lvalue;
}
}################# end tryLocal

This works.

#!/usr/bin/perl
&tryLocal("name=james&color=red&age=12");
exit;
####################
sub tryLocal{
local $in = $_[0];
@in = split(/\&/,$in);
foreach $li(@in){
($lname,$lvalue)=split(/\=/,$li);
$$lname = $lvalue;
}
}################# end tryLocal

Which leads me to say. I was wrong.
As you fall in love with local
(which i have been doing all summer),
you must abandon my old ways.
Create your hash and check $TEMP{$passcode}
instead of $passcode.
