This example shows a simple program in Modula-2 with calls to C procedures.
Special attention has to be given to the following points:
- Modula-2 handles only far code and far data. Use the 'far' keyword in
C for all data and procedures used also in Modula-2, or compile with the
C compiler option /AL to use the large memory model.
- C doesn't provide real string variables. Strings are handled with
pointers to arrays of characters. Use pointers also in Modula-2 or
use the knowledge about the implementation and pass the string
length along with the pointer.
