Usage
Call this function after calling InvokePBFunction or TriggerPBEvent to access the updated value in an argument passed by reference.
JavaScript scripts must use this function to access arguments passed by reference. VBScript scripts can use this function if they established the argument list via calls to SetArgElement.
Examples
This JavaScript example calls the GetArgElement function:
...
theArg = f.textToPB.value;
PBRX1.SetArgElement(1, theArg);
theFunc = "of_argref";
retcd = PBRX1.InvokePBFunction(theFunc, numargs);
rc = parseInt(PBRX1.GetLastReturn());
IF (rc != 1) {
alert("Error. Empty string.");
}
backByRef = PBRX1.GetArgElement(1);
