Well, a string variable is simply an array of characters, so you could just loop through the variable and assign each element(letter) with a space appended to it (unless it is already a space?) to a new variable. Consider how you deal with the last element - ie does it need a space appended? -- David Robley | WEBMASTER & Mail List Admin RESEARCH CENTRE FOR INJURY STUDIES | http://www.nisu.flinders.edu.au/ AusEinet | http://auseinet.flinders.edu.au/ Flinders University, ADELAIDE, SOUTH AUSTRALIA
