Reference

Every built-in, every constant, every diagnostic.

Use these pages when you need an exact spelling, range, signature, return value, diagnostic, or constant.

• Language and operator reference

• Core public built-ins

• Additional public built-ins

• Combo controls and commands

• Constants index

• Compiler diagnostics

• Scope, counts, and target limits

The reference is intentionally detailed. Newcomers can stay in the learning chapters and follow links here only when an exact fact is useful.
