You can use a character variable to contain a valid executable command, then simply supply that variable to the RUN command. Something like: DEFINE cmd CHAR(80) : : LET cmd = "myscript ", myparam1, " ", myparam2 RUN cmd Just be very careful of spaces between command and parameters, and between parameters. If you need to send multi-word parameters, then don't forget to enclose them in quotes, like so: LET cmd = "myscript '", myparam1, "' '", myparam2, "'" RUN cmd If you need double quotes, then don't forget to quote them, as follows: LET cmd = "myscript \\"", myparam1, "\\" \\"", myparam2, "\\"" RUN cmd Hope that helps, -- Mark. +----------------------------------------------------------+-----------+ |Mark D.
