Suppression of Command Line Activity During Lisp Processing

Is it possible to suppress command line activity with a message, such as:

(Prompt "\n***  Working, Please wait ......\n")

During the time taken to process a lisp routine, or a number of lisp routines?

This doesn't appear to work in the following format, however, it should be noted that I do use "command" in lisp routines.

(Defun C:Test ()
(Prompt "\n***  Working, Please wait ......\n")
(LispFunction1)
(LispFunction2)
(LispFunction3)
(princ)
)

Cheers.

Suppresses command prompts: (setvar 'Cmdecho 0)

Suppresses messages: (setvar 'Nomutt 1)

Hides Command area: (command "_.COMMANDLINEHIDE")

Thank you Ahankhah,

I think 'Nomutt' is what I am looking for, I will test it tomorrow.

Cheers.

I hope it is as you desired.

Another filedia 0 or 1 turns dialogue boxes on or off usefull in some cases. Note is not 100% for all commands.

Thanks guys,

I am familiar with CMDECHO and FILEDIA.

No matter how many system variables, I think I know, I always learn a new one!

Cheers,
