standard GNUCobol file?
I compile the utility with

Any ideas?

Yes, I am on this list. In my Linux system, the GnuCOBOL copy files are
located in: /usr/local/share/gnucobol/copy and the version of GnuCOBOL I
am running here is identical to yours: 3.2.0.
There may be a setting that is necessary to export the copy directory
identity, but I do not know what that might be. I only know that it has
been discussed before. I will see if I can research it, but perhaps
someone who knows the answer without research will reply.

The warnings are all from clang (in your setup the C compiler that is executed by cobc after it generates intermediate C):
warning: illegal character encoding in string literal [-Winvalid-source-encoding]
If I understood the information I've checked correctly, then the issue is that clang has the limitation that it expects all source files (the ones that cobc generates) to be in UTF8. And by default it warns if literals are not valid utf8.
You can try two things:
* tell cobc to encode all non-plain 7bit ascii characters: LC_CTYPE=C cobc -x maketape.cbl (we check for printable characters of the current ctype and encode the others - don't export LC_CTYPE in general...).
* tell cobc to tell clang to shut up: cobc -x -A -Wno-invalid-source-encoding maketape.cbl (you could also do that "permanently" by exporting an environment variable)

Hi
I am trying to compile Jay Moseley's tape utilities on my Intel Mac
https://www.jaymoseley.com/hercules/awstape_utilities/cobolawsutilities.htm
Jay is in cc:, since I don't know if he is on this list.
Here is the version of the compiler I use.

Yep. Both tricks - the LC_TYPE and -Wno-invalid-source-encoding - work.
Thank you.
Jay, I found the copybooks. They are in the same directory on my Mac; I
guess brew put them there.
All the best
Marco
