Hi I am running tr.exe 33,280 bytes 11/11/1999 for Win32 on W2k Professional. Trying to translate the string @ @ (at-space-at which is \100\040\100) to ! Have tried the following: tr -s "@ @" ! tr -s \100\040\100 ! tr -s @\040@ ! tr changes all occurrences of \100 and \040 to !, regardless of the sequence of characters. Thanks for your help Bob Smith-Vaughan ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
