If you specify SFLPGMQ (with its named field) and the SFLINZ keyword on the subfile control record format, you build the entire subfile with one output operation directed to the subfile control record format. On the output operation, the OS/400 program initializes the subfile with all messages that are on the program message queue whose name is in the SFLPGMQ field. If necessary, the OS/400 program extends the subfile to contain all messages on the queue. For this function, the SFLMSGRCD, SFLMSGKEY, and SFLPGMQ keywords must be specified with the subfile record format (SFL keyword). The SFLPGMQ and SFLMSGKEY keywords are ignored for this function and your program need not set the values of their fields.
