in reply to Problem in finding hash keys

There are no "special" characters for hash keys. On my system it finds a hash item with key ">G7USM1/27-197 [subseq from] G7USM1" without fail.

Try a Data::Dump of your hash to make sure that entry indeed is present.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
