Problems compiling Micro Focus COBOL program as GNT

I am trying to compile a Micro Focus COBOL program with a Dialog
screen into a GNT file.  From the research that I have done, the
command line I should be using is cob -ug <filename>.  I get an error
saying that -u is not a valid flag.  Any suggestions on why I am
getting this error, and how I can go about compiling the program?

Hi.

Can you provide details of which Micro Focus product you're using, which
platform, and the exact command-line you're specifying?

Please also provide the output of

cob -V

thanks.
