Hi Monkeys, my input will look something like this: 
NTE||L|obr note
OBX|NM|aaA..^Haem^RD2|7.5|g/dL|13.0-18.0|OR|
NTE||L|obx note 1/1 for 3058
OBX|NM|dBf..^TWC^RD2|8.9|10*9/L|4.0-11.0||

And basically, if the line starts with OBX, then I want to take the characters between the second pipe and the ^ and prefix uppercase characters with "U" and lower with "L". So, aaA becomes LaLaUA (this is for text comparison elsewhere in a lang. that doesn't support case-sensitive string comparison). This is my main code: 
  if(m/(^OBX\|)([^\|]*\|){2}([^\^]*)(.*$)/){
    my $pre = $1 . $2;
    my $read = $3;
    my $post = $4;
    $read =~ s/[A-Z]/U$&/g;
    $read =~ s/[a-z]/L$&/g;
    $_ = $pre . $read . $post;
  }

I was just curious is there was a more elegant way to do this - preferably a single s///, rather than one match and two substitutions. Thanks in advance...
