| | The following program parses the string and stores the substrings in an array or list. So far I haven't figured out how to put the contents of this array into a hash that would be useful. [CODE]#!/usr/bin/perl -w use strict; $_ = "OWN - NLM " . "STAT- Publisher " … |

| | jice's solution looks good to me, unless you want only a slice of the second data line and want to convert the FCITC string into an integer. Here it is with a couple of minor changes to do that.
