sfmc/amp-set-requires-target

Require set statements to have a target variable.

Why This Rule Exists

The correct form of a set statement is set @variable = expression. A bare set = expression with no target is either a parse error or produces undefined runtime behavior. This always indicates a typo or incomplete code.

Settings

Setting	Values	Default
severity	"error" | "warn" | "off"	"error"

This rule has no configuration options.
