kActionCase

Supported Flags: none Param1: [(CaseStatementActionAtoms)]

Provides a conditional control structure. The CaseStatementActionAtoms allow for pairs of expressions and actions to be defined. The list of expressions is evaluated, when an expression evaluates to true , no other expressions are evaluated and the list of actions associated with that expression is executed.

Nested control structures are possible, since they are themselves actions.

kActionWhile

Supported Flags: none Param1: [(WhileStatementActionAtoms)]

Provides a looping control structure. The WhileStatementActionAtoms define an expression and a list of actions to be defined. While the expression still evaluates to true , the list of actions is performed.

If your list of actions does not contain an action which will eventually cause the expression to evaluate to false , the control structure will be caught in an infinite loop. Nested control structures are possible, since they are themselves actions.

kConditionalAtomType

This atom is used in conjunction with the case and while statement actions. It contains atoms which desribe a Boolean expression and an action list, which is executed on the condition that the Boolean expression evaluates to true.

In both cases, this atom is a child atom of the action's only kActionParameter atom. The atom contains two child atoms, one of type kExpressionContainerAtomType and one of type kActionListAtomType .

kActionListAtomType

This atom is used to contain an action list to be performed by the kActionCase and kActionWhile actions when an associated expression evaluates to true. In both cases, the atom's parent is of type kConditionalAtomType .
