Great, it works like expected.

A big milestone for my port!
I have successfully tested parts of our application now!

I can now make (many) runtime-tests with
the cobc ported application. 

Thanks a lot.

P.S  I have not tested "FD filename IS EXTERNAL"!
       (reason: we have not maked any usage of it;
                   i have to do some other important tasks first!)

       The implemented syntax/semantic  "01 GroupField IS EXTERNAL ... " 
       is now , IMHO,  ANSI-1985 conform!

       Here a some related topics for the TODO list:
         ==> ANSI 1985  "FD filename IS EXTERNAL" 
         ==> ANSI 2002   ... IS EXTERNAL AS "LITERAL"
