Thanks for all the help everybody and the quick turnaround, you've saved
me some valuable time. I wasn't aware of the 'quoted and escaped'
versions of these strings.
To reply to Eric, usually on win32 I just use '/' and let Ruby handle it
for me but the script I'm working on now has to enter this string into a
Windows GUI app edit field and that app doesn't like '/', that's why I
had to convert it myself.
Hal, what did you mean by 'calling p'?
Thanks again,
Ron
