Hi, (if this message is duplicated, my apologies, I keep getting delivery errors) First of all I have to correct myself! You can not change the ! character, but the R character! So you could change the command to !X! or similar. You can do this by using the SCRC (Set Command Recognition Character) command. It is described in the Prescribe reference manual (you can find a link on the undocprint site) Regards, Christoph
