lol...
strict requires that you predeclare vars. It catches things like
$REPORRT further down, which I suspect is a typo.
A few suggested solutions:
use vars qw ( $this_var @that_var %some_other );
That tells Perl that these are package globals, but that you are going
to use them by these names in this package without using the
$Full::PackName syntax.
Whenever you use a variable in Perl, it's global by default.
$g_version = "alpha 1.0";
actually assigns to $main::g_version, but strict requires that you be
explicit about it, instead of just assuming you mean the current
package and creating it if there wasn't one.
You could just say $main::var every time, but that gets old quickly. In
package main, you can just say $::var, but even that is ugly.
Usually, a *better* solution is to use my():
my $g_version = "alpha 1.0";
Will make strict happy, but the variable is no longer a package global;
now it only exists in the current scope (though that might be the whole
file). You can do this in a function or loop to scope a variable to
that block.
