Remarks

"The declared type of <string-argument> MUST be String or Variant", and the target is a bound-variable-expression, so it is a variable. The statement's other operands are not given a rule of their own, but they are used as the statement's runtime semantics uses them: the position and the length as Long (the declared type of the parameters of the Mid function), and the value as a String, so each has to be Let-coercible to that (MS-VBAL §5.5.1.1).

Methods

Evaluate(StaticEvaluationContext, MidStatementNode)

Evaluates the operands of a Mid statement and checks them.

public static ImmutableArray<VBCompileErrorInfo> Evaluate(StaticEvaluationContext context, MidStatementNode mid)

Parameters

mid MidStatementNode: The statement.
