perl -e '($number % 2)?print "even":print "odd"; print "\n";' % is the modulus operator, and returns the remainder from a division of its left operand by its right. 221 % 2 = 1 which is true if tested inside an if statement or whatever. 220 % 2 = 0 which is false in an if statement. Hope that helps. -- Kind regards, Hal Ashburner -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
