5.6.9.4 & Operator
Note
This section describes the implementation of MS-VBAL §5.6.9.4 & Operator.
Runtime Semantics
The & (concatenation) operator is a simple data operator: it validates its operands through
OperatorRuntimeSemantics.LetCoerceNonNullOperand
(RD-VBAL §5.6.9.2 Simple Data Operators).
BinaryConcatOperatorRuntimeSemantics.IsByteArray unwraps a Variant
(VBVariantValue) before matching a wrapped Byte
array.
👉
v1 & v2evaluatesVariants holding arrays the same as declared arrays.
See RD-VBAL §5.5.1.2.12 Let-coercion to Variant
for why a Variant operand must be unwrapped before it is matched against a concrete value type.
