This should help to elucidate the problem you're having, run this and it
becomes pretty clear as to why you're not getting $version in there...
Run this, and see the output:
package foo;
&command::about;
1;
package command;
&about;
my $version = 'test 1.1';
&about;
sub about {
print "$version (c) John Doe\n";
}
1;
C:\source\crap>perl foo.pl
(c) John Doe
(c) John Doe
test 1.1 (c) John Doe
Or, imagine doing this:
print $version;
my $version = "1.1\n";
print $version;
Try, in the future, using a new() method, and creating an instance of the
module (object) before attempting to use methods in it. That way you can
initialize any variables you need before you need them.
