Manual? We don't need no steenkin' manual! :) The only way I've ever
gotten CHDRIVE to work is to feed it a one char argument.
There are errors in the manual, but don't count on a revision anytime soon.

I experienced the same problem, and the work around is as I've already
suggested.  Move the drive letter into a one character string variable
and then call CHDRIVE using that variable.

Let me know how it works.
