Good thought! I played with it and now get the message "test: Specify a
parameter with this command."  I also placed a \ in front of the $WORK_DIR
with the same result.  Sigh....

I put a display in the script just before the awk command to display the
$WORK_DIR variable and it does have data in it.  Any thoughts on this new
wrinkle?

I really didn't think this project would be so time consuming!

Your outer quote need to be double quotes so that  the shell variables are
interpolated.  This means that you have to backslash-escape any double
quotes and dollar signs with the double quotes.
i.e.
awk "\$2 != $WORK_PID {system(\"export  cmmain_flag=2\")}'
