5.4.2.19 Exit Property Statement

Note

This section describes the implementation of MS-VBAL §5.4.2.19 Exit Property Statement.

Syntax

AST node	Instruction kind	Notes
KeywordStatementNode (`Token`: `"Exit Property"`)	`ExitProcedure`	No resolved target.

Exit Property lowers to the same InstructionKind as Exit Sub and Exit Function: ExitProcedure (RD-VBAL §3.5.2 Instruction).

Static Semantics

An Exit Property must be inside the body of a property declaration (Property Get, Property Let or Property Set); in a Sub or a Function it is VBC09315 (ExitPropertyNotAllowedInSubOrFunction). The rule is ExitStatementStaticSemantics's, applied when the kind of the procedure is known (RD-VBAL §5.4.2.18 Exit Function Statement).

Runtime Semantics

The executor dispatches the ExitProcedure instruction, as for Exit Sub (RD-VBAL §5.4.2.17 Exit Sub Statement).

For a Property Get, the function result variable is read back however ExitProcedure was reached: an explicit Exit Property, or reaching the end of the body. The value read back is the call's result (RD-VBAL §5.3.1.11 Procedure Invocation Argument Processing).

Implementation

RDCore.Runtime.Execution.ProcedureExecutor dispatches ExitProcedure instructions.
RDCore.Runtime.Execution.RuntimeProcedureInvoker reads the function result variable back from ICallStackFrame.ReturnValue.
