Re^5: i need help in subroutines

[Corion]

Put the following line near the top of your script:

use diagnostics;

Perl will then tell you the cause of the error. The diagnostics pragma has many helpfull hints. Please also read the Writeup Formatting Tips and use the Preview feature so your posts are readable to others. Perlmonks uses HTML for formatting.

thanx Corion,,,, i am not sure whether the following code is write ======================================

#file1 is in  "d:/test.pm"                                 
sub uvaraj                                                 
{
$name='ramu';
print 'uvaraj is a good boy in nature but...';
}

===================================

#file2 is in "d:/run.pl"                                   
use lib 'D:/';
use test;
&uvaraj;

==================== i run the second file, it is giving error as "test.pm didnt return a true value"

You appear to be using the first file you mention ('d:/test.pm') as a module, and it is complaining that it did not return a true value. Modules must return a true value to let perl know they loaded correctly. Try appending the following as the last line of that file, and see if it makes a difference:

1;

In addition to the resources previously mentioned by Corion, et. al., you may also wish to look at the Tutorials section of this site (especially tachyon's Simple Module Tutorial), and in the documentation that comes with perl at perlfaq7 (question "How do I create a module?"), as well as perlmod, perlmodlib, perlmodstyle, and perlnewmod.

HTH.
