The IEWBIND macro issues the LOAD macro for the IEWBIND entry point on the STARTD call and the DELETE macro at the completion of an ENDD call. In order to retain addressability to the binder on subsequent calls, the entry point address is saved as the first word in the dialog token. This token must not be modified in any way between binder calls.

If your program does not use the IEWBIND macro, you must cause the binder to be loaded for entry point IEWBIND. Subsequently, each function call is executed by calling the IEWBIND entry point with a parameter list.
