I have a "c" program that returns an integer value.  How does one run this
program from within a csh script and access the returned value?  I have
tried various forms of the following lines with no luck.

#!/bin/csh
#
#  NOTE: WF_DIR is an environment variable.
#
set intro_data = "data"
@ nobjs = `"$WF_DIR/lbin/read_intro $intro_data"`




When run, this script yields the following error message on a Sun4-280:

/usr/local/wave/lbin/read_intro data: Command not found.

If I change the csh line to the following, it runs properly but does not
(of course) return the integer value.

$WF_DIR/lbin/read_intro $intro_data

Does anyone know what's the deal?
