Conditional operators execute an operation if one or more preconditions are fulfilled. If these conditions are not fulfilled, they can possibly execute another operation.
OM offers two conditional operators : omif and conditional , which operate according to the following paradigm : "IF A, THEN do B, ELSE do C".
Note : "A" can be the result of another opration or a condition defined by a predicate.
To access the omif and conditional operators, select a menu item in the
Kernel / Control menu.
