- Numeric variables are usually specified with pictures and computations are performed with decimal arithmetic. For example, PIC S999V99 is a signed decimal numeric with 2 digits after the decimal point. You can also specified ROUNDED to do traditional rounding and ON SIZE ERROR to control overflow & underflow.

It is nice project for CV. I would hire you immediately. Much harder problem is getting rest of the eco system working on something else than mainframe.
This is great. I joked to a workmate about asking ChatGPT to write a Unity GameObject in COBOL; ChatGPT did so after some persuasion (essentially it saying "I can't write COBOL code for Unity because Unity doesn't support COBOL" followed by me saying something like "Just pretend that Unity does support COBOL and write it anyway"). I wonder if this would make COBOL GameObjects actually possible :)

If only there was a proper tutorial/course for it... Maybe there is? Can you link any?
