Mark - I have ActivePerl on Win2K and 'perldoc' works fine. ActiveState should have put its 'bin' sub-directory in your path; 'perldoc.bat' is there.

Thanks for your help and your patience with my density. I would like to see if I have this straight now. Which may also lead to another question. :-) transliterate : Websters New World : to write in the characters of another alphabet. The c/ switch passes over the characters in the scalar found in "pat1" leaving them unchanged and renders all others to hex. ($value=~tr/pat1//c;) The /d deletes all characters not found in pat1. If this is so, why would one convert them to hex and then delete them also "/cd" a is done in $name =~ tr/a-zA-Z0-9-_ .,:;'&$#@!*()?-//cd; I didn't write the statement above, I pulled it out of a script that I am trying to use as an example for my own education about perl. I wonder why not just use /d since that is the end result anyway. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
