You should reproduce the error so we don't have to, but I know the error already. Something like "cannot modify die in assignment"? The ?: operator binds more tightly than the = operator, so your code reads like (!$opt_Z ? die "..." : $mkt) = $opt_Z; This makes Perl think you're going to assign to either $mkt or the return value of die(), and the latter is impossible. Either parenthesize the assignment: !$opt_Z ? die "..." : ($mkt = $opt_Z); or swap the two: $opt_Z ? $mkt = $opt_Z : die "..."; Or better yet, use the following idiom: $mkt = $opt_Z or die "..."; -- Jeff "japhy" Pinyan [EMAIL PROTECTED] http://www.pobox.com/~japhy/ RPI Acacia brother #734 http://www.perlmonks.org/ http://www.cpan.org/ ** Look for "Regular Expressions in Perl" published by Manning, in 2002 ** <stu> what does y/// stand for? <tenderpuss> why, yansliterate of course.
