As the Perl was installed in school's desktop, I dare not to make any changes for installing a new module, I did tried once, then got some permission denied error.

See Yes, even you can use CPAN

You will need an older version of Regexp::Common, since the newest one requires perl version 5.010 (v5.10.0) as minimum. Regexp-Common-2016020301 is the last release whose requirement is below 5.10.0 (it requires 5.00473).

You dont't even need to install it. Quick and dirty test setup:

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
