5250 Terminal Emulation Programmer’s Guide
Screen Design Aid
This chapter, along with your Screen Design Aid (SDA) documentation,
can help you resolve occasional questions concerning discrepancies that
may arise regarding attribute selection and the capabilities of the terminals.
This chapter includes information you may not need, because you can use
your SDA to do much, if not all, of the programming to handle com-
mands and orders for the network. This information is provided to assure
you have the most accurate and detailed information available and to de-
scribe variations from the 5250 data stream where they occur.
If you are comfortable using the SDA on your host computer, you can flip
through this chapter to find out which commands and orders the terminals
support. You can then read Chapter 7, “Extended Commands,” which
describes the extended commands you can use to do operations beyond the
capability of the IBM Display Station.
Applications
If you need to write applications specifically for the terminal, it is recom-
mended that you use the corner mode window onto the IBM Display Sta-
tion and write programs using the portion of the display available without
moving the window. This is the most ef ficient method for developing cus-
tom applications for the terminal.
