Updated Nov 21, 2025
Installation Setup
Obtain a BCPL compiler or interpreter (e.g., Chipmunk, OBCPL)
Install compiler on your OS (Windows, Linux, macOS)
Set environment variables for BCPL paths
Compile sample programs to verify installation
Run test executables or interpreted scripts
Environment Setup
Install a BCPL compiler/interpreter
Set environment variables for paths
Create directories for source, binaries, and libraries
Compile test programs to verify setup
Run sample code to ensure functionality
Config Files
*.b - BCPL source files
Lib/ - runtime and helper libraries
Bin/ - compiled executables
Docs/ - documentation and notes
Tests/ - test programs and examples
Cli Commands
bcpl file.b - compile BCPL source
bcompiler file.b - generate executable
brun program - run compiled program
