When No-Wait I/O is Unnecessary It is possible to achieve some overlap of host and HP 3000 processing without using no-wait I/O. With standard blocked I/O, you can issue TRAN3270 to start host processing and then do some local (HP 3000) processing before calling RECV3270. If the host completes processing and sends new data to your device, this data is stored in the internal screen image to wait for your RECV3270 call. This method of I/O processing may be acceptable to you if you do not have to worry about the host modifying your internal screen image again before you call the RECV3270 intrinsic.
