18.104.22.168 RXINI — The Initialization Exit Handler RXTER and this exit handler are a bit different from the others. RXINI provides the application programmer with a method of getting control before the execution of the script starts. Its main purpose is to enable manipulation of the variable pool in order to set up certain variables before the script starts, or set the trace mode. It has only one subfunction, RXINIEXT, called once during each call to RexxStart(): just before the first REXX statement is interpreted. Variable manipulations performed during this exit will have effect when the script starts. As there is no information to be communicated during this exit, the value of ParmBlock is undefined. It makes no difference whether you return RXEXIT_HANDLED or RXEXIT_NOT_HANDLED, since there is no situation to handle.
