RE: how to advice please : rules with dependencies created incommands

[PATTON, BILLY \(SBCSI\)]

The CREATE variable was just for the purpose of a demo.  Where the
values in CREATE will com from will be in  parameter file passed to
prog_1.  The Makefile will have no knowledge of what needs to be built.
I think I can use Tom Tromey's method of auto-dependency to accomplish
this.
