VBC09333 — Variable required

Severity: Error · Family: VBC (static semantics / abstract syntax tree) · Source metadata: VBCompileErrorInfo

An expression that is not a variable is where a statement requires a variable: a value is to be assigned into it.

MS-VBA reports the same error: Variable required - can't assign to this expression.

This code is raised for the statements whose operands the specification says "MUST be classified as a variable" (MS-VBAL §5.6.1): MidStatementStaticSemantics and FileStatementStaticSemantics.

How it is raised

Situation	Example	Resolution
The target of a `Mid` statement is not a variable.	`Mid("abc", 1) = "x"`	Assign into a variable that holds the string.
The target of a `Line Input #`, an `Input #` or a `Get` is not a variable.	`Line Input #1, "x"`	Read into a variable.
The expression is a constant.	`Input #1, Limit`, for `Const Limit = 10`	Read into a variable.

Notes

Only an expression that is certainly not a variable is reported: a literal, the result of an operator, and the name of a constant. Which of the others - a member access, an index - is a variable depends on what it resolves to, and is not judged here.
