| Text: | This guide describes the Silicon Graphics 3270 high-level language application program interface (HLLAPI). It explains the programming tools that are available to customize the user interface to the IRIS 3270 Emulator, automate 3270 interactions between Silicon Graphics systems and the IBM host, and use Silicon Graphics Message Mode facilities to increase throughput. This guide is written for HLLAPI application programmers who need comprehensive information delivered in an economical style: it explains departures from IBM PC Assembler HLLAPI, lists all Silicon Graphics HLLAPI capabilities, then presents a functional description of each subroutine that implements these capabilities. It also provides troubleshooting advice, and appendixes of error messages and scan code and buffer code tables. |
