thanks MrBcx
it compiles and runs without issues 👍

Here is a version that humorously demonstrates the enhanced CHR$().

Requires BCX 8.2.9 and any compiler.

Woops!   

Sorry about that.

I forgot that I used some new capabilities that I added to the forthcoming BCX 8.2.9.

I've replace the code in the original post with a version that builds with the currently released version of BCX

I wrote the original 35 years ago using TurboBasic for MSDOS.

Now updated to run in Windows console window. 

It uses several unicode characters for the graphics and the source code
contains several useful console mode SUBS that you can use in your own
console mode apps.

This builds in BED with all the compilers. 

Remember to build this as a console mode app, not a GUI.

Game play is controlled entirely by keyboard.
