System with manual options

Hi

I was wondering if there was a way to run system when there
is e.g. a C program which is not totally command-line driven.
That is, I have a C program which requires manual input of
options into the shell during the run. I would like to run this program from
R and as far as I have seen system() does not handle manual options (?).

Is there thus a way to use these C programs anyway through
R (i.e. without touching the C programs and fixing the problem in R)?

Thanks a lot for any comments.
