Scope and limits

This edition targets Zen Studio Live and the current 32-bit Zen compiler surface.

Use this page as a coverage audit and a quick target-limit reference. It explains how much of the compiler inventory is documented in this guide; it is not an API or constant lookup page.

Guide coverage

The table compares the reader-facing guide with the complete compiler inventory:

• Covered in this edition: documented for readers in this guide.

• Other inventory entries: target-specific, legacy, validation-only, or non-reader-facing entries outside this edition's scope.

• Compiler inventory total: the sum of the preceding two count columns.
