The half-duplex use of the 3270 is an application, e.g., TMP, restriction: the VTIOC macros support a full duplex mode.

I've more or less gotten used to the "half duplex" use of the 3270 in TSO. What might be nice would be a way, in TSO, to "background" a TSO command like you can a UNIX command. Of course, I must remember that TSO was designed in the days of OS/MVT and is still more concerned with "resource consumption" rather that "user productivity". > > > -- > Shmuel (Seymour J.)
