Hi Connie, thanks for you fast help! You are fully right! Initially, I was not very familiar with this m4 compiler to translate a xxxx.mc file into a xxxx.cf file. Actually, I did the command m4 xxxx.mc > xxxx.cf, but as I know now, it did not work properly. As you can see, I forgot (or I did not know, respectively) about this cf.m4 file which has to be introduced into the command line of m4. Now it works! ;-)))))
Best regards, Guenther Abwerzger
