Winkler's Modula-2 Examples ↩

Directory winkler-examples\ contains Modula-2 code examples from the web page Die Programmiersprache Modula-2 which reproduces two articles written by Eckart Winkler (1987 and 1989).

Code Example

This example has the following directory structure :

> tree /f /a . | findstr /v /b [A-Z]
|   build.bat
|   build.sh
|   Makefile
\---src
    \---main
        \---mod
                Code.mod

Command build.bat-verbose clean run generates and executes the Modula-2 program target\Code.exe :

(* tbd *)

Felder Example

This example has the following directory structure :

> tree /f /a . | findstr /v /b [A-Z]
|   build.bat
|   build.sh
|   Makefile
\---src
    \---main
        +---mod
        |       Felder.mod
        \---mod-adw
                Felder.mod

Command build.bat-verbose clean run generates and executes the Modula-2 program target\Felder.exe :

(* tbd *)

Nullstellen Example

This example has the following directory structure :

> tree /f /a . | findstr /v /b [A-Z]
|   build.bat
|   build.sh
|   Makefile
\---src
    \---main
        \---mod
                Nullstellen.mod

Command build.bat-verbose clean run generates and executes the Modula-2 program target\Nullstellen.exe :

(* tbd *)

WuerfelSpiel Example

This example has the following directory structure :

> tree /f /a . | findstr /v /b [A-Z]
|   00download.txt
|   build.bat
|   build.sh
|   Makefile
\---src
    \---main
        \---mod
                WuerfelSpiel.mod

Command build.bat-verbose run fails to compile the Modula-2 source code; both the ADW and the XDS compiler can't find the identifiers SIZE, PROCESS, NEWPROCESS and TRANSFER in the imported module SYSTEM :
