Portable Intermediate Representation
Read structured examples that show values, operations, subroutines, and the relationship between source instructions and runtime execution.
Explore PIR examplesPractical runtime studies
Learn by reading, running, and changing examples.
Explore compact PIR and PASM programs, follow their bytecode path, and use each example as a starting point for understanding virtual-machine behavior.
Examples are executable explanations.Start with a small instruction sequence, then compare source code with the resulting runtime behavior.
Example library
Choose a small program and trace the model.
These categories preserve the original learning path while presenting it as a practical reference for virtual-machine development.
Parrot Assembly
Inspect compact assembly-oriented programs to see registers, operations, control flow, and explicit bytecode-oriented thinking.
Explore PASM examplesExample conventions
Separate source, output, and guidance at a glance.
A consistent visual language makes it easier to distinguish what you write, what the runtime prints, and what deserves extra attention.
hello.pirsource
.sub 'main'
say "HELLO"
.return
.endHow to read the examples
- Blue marks source instructions and runtime commands.
- Green marks expected output or literal values.
- Red highlights warnings and troubleshooting notes.
- Save PIR files with
.pirand PASM files with.pasm.
Running a sample
From file to bytecode in three steps.
Use a local runtime executable, then compare direct execution with an explicitly compiled bytecode file.
Save the source
Place the example in a file using the suffix expected by its language or assembly format.
Run it directly
Invoke the runtime with the source file and inspect the output or diagnostic information.
Compile and repeat
Write a bytecode file, execute it again, and compare the two paths.
Command reference
Keep the execution loop visible.
The commands below are intentionally small: they make the distinction between source input, compiled bytecode, and runtime output easy to inspect.
