LUA Verbs

A verb is a formatted request that is processed by LUA. An application program issues a verb to request that LUA take some action. LUA verbs are coded as control blocks. Each verb control block has a precisely defined format. To use the LUA facilities, an application program supplies verb control blocks to the LUA API.

An LUA verb always returns immediately to its caller. If the return code is IN_PROGRESS, the application needs to wait for completion of the verb, using the posting method specified in the verb request. See RUI LUA Entry Points for a description of LUA verb postings.

Verb control block layouts are available in the INCLUDE directory. You can use the verb control block layouts and sample programs to help you write LUA application programs.
