Introduction and navigation
Learn the vocabulary, structure, and recommended reading order for the resource.
Documentation resource
Build a clear path through runtime architecture.
Explore PCode Vault documentation for virtual machines, bytecode execution, language implementation, debugging, embedding, and the internal systems that connect them.
Browse the resource
Start broad, then follow the subsystem.
This documentation snapshot is organized as a practical route from orientation to implementation detail.
Running and operating
Review execution workflows, command-line behavior, and runtime operation.
Compiler and embedding work
Find material for compiler authors and developers integrating runtime services.
Reference material
Use opcode and PMC references when tracing concrete implementation behavior.
Design and internals
Study memory, dispatch, bytecode, optimization, and subsystem structure.
Debugging and testing
Connect diagnostic practices with repeatable tests and source-level investigation.
A working model
Read the instruction flow before changing the subsystem.
A small illustrative sequence helps connect source intent with portable virtual instructions.

# Prepare two values
set r0, 21
set r1, 2
# Execute and return a result
mul r2, r0, r1
print r2
haltUse the references in context
Begin with the overview, inspect a compact example, and then use the detailed references to locate the relevant operation or internal component.

How to use these docs
A reliable route from question to source.
The resource works best when conceptual and implementation reading reinforce each other.
Orient yourself
Read the introduction and glossary to establish the core runtime vocabulary.
Trace an operation
Use an example or opcode entry to follow a small, concrete execution path.
Inspect internals
Move into design documents, memory notes, dispatch, or bytecode details.
Verify your understanding
Compare behavior with debugging and testing guidance before drawing conclusions.
FAQ
Questions about the documentation.
What should I read first?
Start with the introduction, then review navigation guidance and the glossary before selecting a subsystem.
Where are the command-line details?
The running documentation covers runtime operation and links to related compiler and execution notes.
Where can I find opcode information?
Use the opcode reference in the documentation contents for instruction-level material.
What are PMCs?
The PMC reference covers a runtime-oriented object category and its documented implementation context.
Does the resource explain embedding?
Yes. The embedding guide is intended for developers connecting the runtime with another application or toolchain.
Are all pages current software recommendations?
No. The documentation is an resource snapshot. Check present-day compatibility and security requirements before using historical software.
