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:

get the tarball
unpack it to some directory (e.g. C:\\Users\me\Desktop\perl)
set the environment variable PERL5LIB to include C:\\Users\me\Desktop\perl\Regexp-Common-2016020301\lib
run your perl program which uses Regexp::Common

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

Hi shmem, thanks for the steps. I am going to google it for a little bit as I am not too familiar with linux environment yet. At the mean time, is there any other method that I can achieve my goal? like storing the found or empty value into variables ?	[reply]

... any other method ... storing the found or empty value into variables ? Did you take a look at the code here? (Update: Also here.) And if you need a quick-and-dirty replacement for `$RE{num}{real}` from Regexp::Common if you have difficulty installing it, try `my $rx_amount = qr{ (?> [-+]? (?: \d+ (?: [.] \d*)? \| [.] \d+)) }xms;` It's semi-tested and should be enough to move forward with. Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]
