Re: Regexp experts, come to rescue!

One problem is you are performing the second and third regexps on the default variable '$_'. I.e. what your code is actually doing is this:

if ($MType =~ /-[45][15j]/ig  || 
    $_     =~ /[123][a46]u/ig ||
    $_     =~ /7[9l][hb]/ig   ) {
      print "\"red\"";
} else {    
      print "\"#CCFFCC\"";
}

I would also offer '$MType =~ /^(-(41|55|jj)|(1a|24|36)u)$/' as a regexp that would match all the cases you list (and no others).
However, if they are the only cases you want to match, creating a hash and checking for the existence of keys would be more efficient:

my %matches;
foreach (qw( -41 -55 -jj 1au 24u 36u)) {
    $matches{$_} = '';
}

if (exists $matches{$MType}) {
    print "\"red\"";
} else {
    print "\"#CCFFCC\"";
}

In that line, you may be better of using `sub match{ my $MType = shift; $_ eq $MType and return 1 for ( qw(-41 -55 -jj 1au 24u 36u )); }` [download] Hope this helps, Jeroen "We are not alone"(FZ)	[reply] [d/l]
