What do you not understand? As the page remarks, it's not as big a problem as people make it out to be. Perl does a fine job of being able to automagically convert back and forth. If you can remember that text used in a == comparison will be 0 ($text == 0 is true), you should be safe. If you need to test against 0 itself, test to see if the string is equal to '0'. -- Brett http://www.chapelperilous.net/ ------------------------------------------------------------------------ Go 'way!
