Hi Steve, thanks for your reply.
The "system" command documentation in your link is exactly the same as in the MuPAD 4.0 that I have.
I am aware that ! suppresses output. That is why I wrote...
> !date/t > comm_file > (no error code [silent], no file produced)
with the notation [silent] as shown.
I had checked that DATE/T works at the DOS command prompt. It is not sensitive to case.
Can you please try it on a Windows O/S and see if it works for you.
