>Description:
A CGI script written in UNIX shell script format calls the "expr" command to
perform simple arithmetic calculation (addition).  The resulting variable has
no value.  This shell script was working fine with the CERN Server used previous
ly.  This same behavior was noted in other similar scripts as well.
