Please tell how to build this with e.g. m2c

[vonbrand]

m2c-0.7 is the only Modula 2 compiler I can get to work (after some tweaking) here on Linux.

Please do add instructions. It isn't even apparent which is the program (not used module) file!

[trijezdci]

m2c is alright for study, like compiling Wirth's example programs but it is not recommendable for serious use.

On Linux I recommend you use the MOCKA compiler: https://github.com/trijezdci/MOCKA/tree/master/ver1807

Note M2BSK is still work in progress and there are some source files that still need to be back ported from M2PP.
