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.
