Using cobolgl with emacs / gentoo gnu+linux or z/OS

[sylvianhemus-new]

Hey, I'm learning cobol and wanting to make a game with it. I'll probably start with just making text based game then later add graphics.
I usually program in emacs and on gentoo gnu+linux, would like to try to build the game for z/OS. Do you have any suggestions for a noob on where to look for guided research? Like imagine if I was your student. Not asking you to do the work for me but if you can recommend where to begin.

You will most likely not be able to build this project as it uses windows specific API in order to draw graphics. I do not use linux nor z/os but if you just want to get into cobol I would recommend looking into GnuCOBOL as it is free and has some neat features like transpiling to C, I've also seen people use C libraries like SDL in order to draw graphics.

As for guided research I do not really have any good resources, I think the GnuCOBOL manual could be of help. COBOL is quite old and not mainstream so most resources are in form of manuals or articles.

Hope it can be of some help.
