Extended Rule Keywords and Commands

Generally, a keyword is a fixed use of a word that indicates how the programming language must be interpreted. There are two types of keywords—execution control keywords and commands. Execution control keywords control the flow of execution of the defined rule. These keywords evaluate conditions and perform looping operations. The second type of keyword is a command. Commands perform actions on variables and are responsible for the movement of data.

For information about specific keywords and commands, see Alphabetical Language Reference.
