One modification: make sure any output intended to be seen by the user is sent to stderr, otherwise ALL output from "prog" will be assigned to VARIABLE. Make sure that the only output from prog that goes to stdout is what is intended to be assigned to VARIABLE. For that matter, should you need to, "prog" need not be a C program. I have written a number of shell scripts that do the same thing by redirecting all prompt output to stderr (echo ..... >&2). Randy
