Hi All
I have two data files that I want to reconcile. For ease, I have loaded these into two arrays. So basically, I'm trying to find any items in one of the arrays that arent in the second array (and print 1 message if any differences...)
I tried  print STDERR "DEBUG YYY \n" unless map {grep \$_\, @ingfile} @sybfile; But it doesn't quite work? Suggestions etc... Please.
