If I code:      C          Key1       Chain   SomeFile

then I have to find Key1 to know what I'm using to chain with.
I also have to move fields into the ones defined on the key list.

If I code:      CF    CUST#:ORDER#    Chain  SomeFile

then I immediately know what my composite key is plus I can
use various fields (i.e. OCUST# or CCUST#) as long as the
attributes are similar. (Hans) I know the above syntax is not
exactly write, but I was trying to match the sequence of the
C-spec with Factor1, Op Code, Factor2.
