​here's one idea: write to a file ie "pwd >foo"
then read back the file, as so:

​#! /usr/bin/env gforth

s" foo" r/w create-file

drop  \ really should check for errors

variable fileid
fileid !

s" echo You think this works\?  >foo ; pwd >>foo " system

create filecontents 200 allot
filecontents 200 fileid @ read-file

filecontents 200 type
filecontents 100 dump

fileid @ close-file

bye

​There probably is a way to do it with pipes, but it is beyond me.​
