Re: use, require, do or what?

Just two suggestions:

Don't use loose .pl files. Make proper modules, with their own namespaces. perlmod is your friend.
Don't make assignment to variables inside your modules. Return the value of the calculation from a function, and use that.

What you have will be something like:

use strict;
package Module1;
use Exporter 'import';
our @EXPORT_OK = qw(compute_value);

sub compute_value {
  # do the computation
}

1; # this is required, see perldoc perlmod
[download]

in the file "Module1.pm" and something like:

use strict;
use Module1;

my $variable1 = Module1::compute_value();
[download]

or:

use strict;
use Module1 qw(compute_value);

my $variable1 = compute_value();
[download]

in your main script.

Creating a proper module isn't an option. I have to work within the constraints of my employer's dev environment. The whole purpose of the code is to assign values to variables. I over-simplified in my examples. Basically, the code is to take ARGV and convert it into a date, and if there is no ARGV it creates the date based upon localtime.	[reply]

Could you please explain to me exactly _how_ your employer's dev env precludes you from making proper modules and subroutines instead of loose .pl files? Modules can be put in the current dir, just like your .pl file in your example... []s, HTH, Massa (κς,πμ,πλ)	[reply]

We only use modules that are a part of the core distribution of Perl.	[reply]

Wait, so then why are you trying to put the variables in another file? -Actualize	[reply]
