The LUA VCB Format

The LUA verb control block (VCB) is called LUA_VERB_RECORD. It is a structure with two parts:

• A structure, LUA_COMMON, which is used for all the LUA verbs.
• A union, LUA_SPECIFIC, which is used only by RUI_BID, SLI_BID, SLI_OPEN, and SLI_SEND.

The following topics describe the VCB and its parts.
