Call Method
The Call method runs the procedure specified by the prochandle object.
This method has the following syntax:
[retval =] prochandle.Call(arguments)
The arguments are specified exactly as in a callproc statement (see Callproc Statement).
If prochandle is a local procedure that is part of a frame or a global procedure, the following restrictions apply:
Do not invoke the Call method after the frame or global procedure in which it was defined has finished running.
Invoke the Call method only from the thread in which the GetProcHandle was issued (an openframe creates a new thread).
These restrictions do not apply to a prochandle that represents a global procedure or a local procedure that is defined in a user class script.
Note:  To access the prochandle for a user class procedure, do not invoke the GetProcHandle method directly from the initialize (constructor) code block. Instead, use a defined method, calling it from the initialize block if necessary.
Do not use the Call method in an expression. It can be used only by itself in a statement or on the right side of an assignment.
