S211KENO@HTIKHT5.BITNET (11/16/85)
I'm writing a command procedure to authorize a new user. One of the things this procedure does is inquiring the new user's password. Of course I do set terminal/noecho before the INQUIRE-statement, but onfortunately the password is still in the recall-buffer. Does anybody know how to clear the recall-buffer ?

It appears the DCL routines which extend the terminal driver's memory don't agree with the terminal driver itself about whether to save non-echoed input. The driver's probably right since you're not very likely to be editing a command you can't see... To do it the driver's way, use Read rather than Inquire: $ read/prompt="Password: " sys$command password I think this should solve your problem. (An explicit Read to the terminal is more often used when you want the input precisely as typed (no conversion to upper case...), or when a /TIME_OUT would be a good thing.)

Perhaps the solution is not to use INQUIRE...
how about...
$ READ/PROMPT="Password: " SYS$COMMAND password
this doesn't enter anything into the RECALL buffer.
Share and Enjoy...
