Abstract
A method and system for optimizing the passing of a parameter to a routine is provided. It is determined if any parameters are aliased in a call to a called routine. In the absence of aliases, calling routines passing parameters to called routines using “call by reference”. Recovery mechanisms are provided, when appropriate, when unhandled exception occur during execution of the called routines. According to the method, a recovery mechanism includes encapsulating the called routine and call statement block with a “catch-all” exception handler. The response to an otherwise unhandled exception includes restoring the actual parameter using a stored copy of the actual parameter. The restoration is performed by making a handle point to the copy of the actual parameter that was made before execution of the called routine.
