LU 6.2 and Horizon equivalences

Overview

In terms of the LU 6.2 architectural standard, Horizon implements LU 6.2 "mapped conversation" support, using the "base subset" of LU 6.2 options. In addition, some optional verb sets are implemented: explicit flush, PIP data, attribute query, and security.

The tables in the following sections map Horizon programming statements and their parameters and status codes to corresponding terminology used in standard LU 6.2 architectural documents. The SOUL column of the tables is formatted according to the following conventions:

• Items in full capitals are keyword parameters.
• Items in lowercase are positional parameters.
• Items in parentheses are parameters on either DEFINE commands or network control commands; the command name is given in initial capitals.

LU 6.2 and Horizon verb and parameter equivalences

The following table maps LU 6.2 verbs and parameters to SOUL statements and parameters.
