Hi, I'm just coming to terms with regex in Perl and have been looking a a problem using Perl. I have a solution but it looks a bit clunky to me and I wonder if some Perl experts can cast there eye over it and suggest ways of improving the regex I've created. Your help is appreciated.

I have several words I need to match when a user inputs some data. The format of the words are as follows

CDC_(followed by any number of alphanumeric characters)_(followed by any number of alphanumeric characters)

DDCSMR(followed by any number of alphanumeric characters)

DDCRMR (followed by any number of alphanumeric characters)

e.g. CDC_ABCTST_NUM1, DDCSMR12AFT, DDCRMRXX5Z1

all characters are upper case . The words all have the same format *_*_* or DDCRMR* or DDCSMR*

here is the code 
#!/usr/bin/perl

use warnings;
use strict;

while(<>) {

if(m/\bSYB_([A-Z])+_([A-Z0-9])+\b|\b(ASESMR|ASERMR)([A-Z0-9])+\b/) {pr
+int "Found a match $_\n";}

}

This matches the words but I can't help thinking it could be improved upon.
