    This looks like exactly what I remembered. Thanks so much. If it's not too imposing, however, could you explain why/how this works? OTOH, I may be able to find info on "?" and ":" as operators in Programming Perl. :-)

      You will find information about it in the Camel book... the "?" and ":" comprise a single operator called the "ternary" or "trinary" operator, so look for that in the index. You can also find information about it in perlop. Search for "Ternary".
