By narrowing down a problem with generated code, i stumbled about this effect:
Program 1 is not working, compiled with cobc -x. Compiled with cobc -C you can see in the C-program, that the procedure division is empty.

This program does nothing, when you run it. The text is not displayed, nor is a error message given when compiling it with cobc -x dbtest.cob
But THIS program does what it should do, display the text.

The only difference is, the first program has an AUTHOR and DATE-WRITTEN, the 2nd not.
Try it yourself and see :D
