AutoCAD and BricsCAD. AutoCAD all; BricsCAD V20+. Divergence: type AutoCAD Integer, BricsCAD Short; default AutoCAD 1, may be locked by the CAD administrator, BricsCAD 0; read-only AutoCAD False, BricsCAD True; saved-in AutoCAD Registry, BricsCAD Not saved.

Per-dialect default and settability:

Because clautolisp is headless there is no trust prompt: value 1 means warn-and-proceed (a [sec-untrusted-load] diagnostic, then the load succeeds) and value 2 means block (ERRNO + a security error). --strict defaults to 1, not 2, because it denotes the dialect intersection (portability), not maximum lockdown; a program raises SECURELOAD to 2 itself when it wants hard blocking. Seedable from the SECURELOAD environment variable (precedence setvar > env > dialect default). The gate also applies to open for gated-extension files. Full rules: Normative Rules: Secure File Loading and Trust Model (chapter 11).
