LU 6.2 Application Programming Interface

This data sheet describes HP LU 6.2 API (Application Programming Interface) for both MPE V and MPE/iX operating systems. The term HP LU 6.2 API is used to refer to both HP LU 6.2 API/V and HP LU 6.2 API/iX products. The terms HP LU 6.2 API/V and HP LU 6.2 API/iX are used when a distinction is necessary.

HP LU 6.2 API/V on an HP 3000 Series 37 through 70 or HP LU 6.2 API/iX on an HP 3000 Series 9xx provides HP 3000 users with a way to program HP 3000 application programs for program-to-program communication in an SNA environment.

HP LU 6.2 API implements the LU 6.2 “mapped conversation verbs” for what IBM has named “advanced program-to-program communications” (APPC). Users may write “transaction programs” that use these verbs (or high-level intrinsics as HP has implemented them) in order to communicate with each other, even though these programs may be executing on different systems within the SNA network.

Features

¥HP LU 6.2 API provides:

¥High-level Intrinsics

¥Support for Major Languages

¥Support for IBM Applications

¥Multiple Sessions

¥Peer-to-peer Connectivity

¥Parallel Sessions

¥Support for Remote Attach

¥Compatibility with Other SNA Services

¥Trace Facility

¥Logging Facility

¥User Controlled Sessions Management from Program or CI (CNOS

¥Enhanced Communication Rates

¥Efficient and easy-to-program prob- lem detection and recovery proce- dures.

¥As with all HP SNA services, cus- tomized error and help facilities are provided.
