Capturing output from `system'

Is it possible to capture the output from commands run through
`system'. The obvious solution of

        (with-output-to-string (lambda () (system command)))

does not seem to work in STk 2.2 (SGI, Irix 5.3).

I know of `exec' but then I loose the return value of the command and
using `run-process' does not seem to change anything.


Is there any way I can get the combined effects of `system' (return
value) and `exec' (process output)? Or must I do some trickery with
`exec', getting the shell-command to include the sub-command status in
the output.
