The current development version (e.g. the last snapshot) has words for that, 
0.7.x doesn't. But you can load str-exec.fs from the development branch into 
0.7.3 without problems.

https://github.com/forthy42/gforth/blob/master/str-exec.fs

There are other ways to achieve what you want (of course), but this is 
probably the easiest one.
