Description

The terminal allocation program contains the logic to allocate TCTTE resources to requesting transactions. The request operates in a multiple exchange between the requesting transaction and terminal control. DFHALP passes a SCHEDULE request to terminal control as an ATI terminal control, then responds with an AVAIL command. The requests are represented by AIDs (AID chain manipulations being performed by calls to DFHALP). For LU6.2, DFHALP issues a terminal control allocate mode name macro.
