Function Entry: GETVAR

Name

getvar

Class

Host Interaction Function

Syntax

(getvar varname)

Arguments and Values

varname: system-variable name designator, usually a string

Autodesk documents varname as a string naming a system variable.

Description

Retrieves the value of an AutoCAD system variable.

The per-sysvar entries in §16 System Variables document every varname recognized by AutoCAD 2026 or BricsCAD V25, with the declared type, default, read-only flag, scope, vendor divergence, and source URLs. The normative rules at the head of that chapter (name case-insensitivity, integer clamping, unknown-name semantics, read-only behaviour, angular-units convention) apply uniformly to every getvar call.

Return Values

Integer, real, string, list, or nil.

Autodesk documents that nil is returned if varname is not a valid system variable.

Side Effects

None.

Affected By

host drawing/session state
selected environment profile

Availability

AutoCAD 2026: documented (per Autodesk reference page).
BricsCAD V26: presumed compatible (no contradicting page found).
Status: AutoCAD documented; BricsCAD presumed-both pending Phase 4 verification.
