guru,
I have a file which I call "mysub.pm". It stores *only* subroutines which are use for "mymain.pl" code.
Currently the way I call it in "mymain.pl" is like this: 
#!/usr/bin/perl -w
use strict;
do 'mysub.pm';

# The rest of code

[download]
And it works. How can I change it so that I can call it with "use" like this? 
#!/usr/bin/perl -w
use strict;
use mysub.pm;

# The rest of code

[download]
I tried that code it throws the warning "Command exited with non-zero status 2".

"mysub.pm" simply look like this: 

sub mysub1{
  # somecodes
}

sub mysub2{
  # somecodes
}

# some more subroutines

My second question is. Which is better using "use" or "do" to call it? Which is faster? Thanks ...
