Memorable Monks,

Putting my configuration variables into a separate config file and then 'requiring' it. Finding that if the last variable declaration sets a variable to zero, I get the error message:

"Error - config.pl did not return a true value"

But if I ensure that the last declaration sets a variable to something, anything but zero, it works just fine.

This seems like strange behaviour to me. What's up?

Main file: 

#!/usr/bin/perl -w

require 'config.pl';

print "Content-type:text/html\n\n";
print $variable;

[download]
config.pl 
$v1 = 'something';
.....
$variable = 'hello world';
$flag = 0;

[download]
This config.pl produces the error. 

$v1 = 'something';
.....
$variable = 'hello world';
$flag = 1;

[download]
This config.pl works just fine.

It's not the value ofthe flag in the program - the program doesn't even run. It stops on loading because of this error.




Forget that fear of gravity,
Get a little savagery in your life.
