Write file peculiars

[William "Chops" Westfield <BILLW@SRI-KL.ARPA>]

How can I call WRITE FILE from within a teco macro, and still have
it prompt for the file name, as it does when invoked by ^X^W.
I thought that M(M.M ^R instant extended command$)Write file$
would do this, but apparently this just write out the current file.

Thanks
Bill W
