The following snippet works fine, with local $/ = undef and (string=~//g){$count++} syntax gleaned from Catagorized Questions and Answers.   It's the output end of a script which uses UCD-SNMP to check a passel o' Ethernet switches for port occupancy.  

Here's my question - can repetition of lines 16-19 be re-written more concisely?
