Learn MODULA with Real Code Examples

Install a Modula compiler (e.g., Modula-2, Modula-3)

Set up development environment or IDE supporting Modula

Organize project directories for modules

Compile each module separately or using provided build tool

Link compiled modules to generate executable

Install Modula compiler (Modula-2 or Modula-3)

Set up PATH and environment variables

Organize project folders for modules

Verify compiler installation

Test compiling a simple program

Module files (.mod)

Interface files (.int)

Build scripts or Makefiles

Library modules in subdirectories

Compiler configuration for target platform

m2c module.mod -> compile Modula-2 module

m3c module.m3 -> compile Modula-3 module

link modules -> link compiled modules

run executable -> execute program

make -> automate compilation

Minimal language-level support

UTF-8 or locale handled via OS or libraries

Primarily used in English-based code

Educational tools may add translation support

No built-in i18n like modern frameworks

Runs on supported operating systems

Accessible via console or compiled binaries

Code readable and maintainable

Modules promote reusability

Language itself is platform-independent

Modula is backend/console oriented

Text-based I/O via standard libraries

No built-in GUI support in base language

External libraries may provide GUI support

Focus on logic and modular code design

State managed within modules

Procedures operate on module-level variables

Persistent state via files or external storage

No inherent global state sharing between modules

Encapsulation ensures controlled access

Strongly typed variables and arrays

Records for structured data

File I/O for persistent storage

Type-safe procedure parameters

Module-level encapsulation of data
