in thread OO and <DATA>

dws is correct, but I don't know if the __DATA__ concern is clear enough for newer users. __DATA__ is only read ONCE during the execution of a script, any secondary calls to it will result in an empty string.

I have found it helpful to use something like Text::Template to store information that will be read in multiple times and if setup correctly will allow for edits while the process is running. I like Text::Template for its simplicity, but there are dozens of templating options that might help here.

    Does seek data,0; not work?
[reply]
      Yes, but don't forget to use tell first, lest you spit out the entire program via seek DATA,0,0 : 
      use strict;

my $pointer = tell DATA;

print get_data();

seek DATA,$pointer,0;
print get_data();

sub get_data { do {local $/;<DATA>} }
