user input using nroff/troff

[Brad Appleton]

Ive looked thoroughly in two sets of manuals for this and I still dont 
know how to do it (or if it can be done) ...

What I want to do is have (n|t)roff prompt me for input and then assign
the input to a string, all this without having roff print the input in
the document after it reads it.

Ive noticed that I can print a prompt using the .tm request and I can
read input with .rd request, but .rd immediately inserts the text into
my document. I want a macro named input so that:

.input name prompt

will print prompt to the user, read in input from the user, and assign
the result to the string "name" (using .ds I assume).

Any hints/suggestions would be appreciated!
