My email bounced -so here..
   use the ARGV variables and include
   environment variable on the command line to invoke
   nawk
   ie:
   nawk -f foobar $CMCARC  ....

   in this case ARGV[0] is awk, ARGV[1] is $CMARC.
	since command lines expand, you should get what you want.

	ie your first awk line should look like
BEGIN { aa = ARGV[1]
 ....

 Dont forget to reset ARGV [2] =""
   or you'll end up interpreting $CMCARC as a file to be read in.
