Action operators

Action operator is a syntax construct that describes an operator creating an action.

Action operators can be divided into context dependent and context independent.

Context dependent operators

Context dependent action operators can use external context parameters. They can be used wherever you need to define an action, for example, when creating another action or event. These operators are:

• {...} operator
• ACTIVATE operator
• ACTIVE FORM operator
• APPLY operator
• ASK operator
• BREAK operator
• CANCEL operator
• CASE operator
• CHANGE operator
• CHANGECLASS operator
• COLLAPSE operator
• DELETE operator
• DIALOG operator
• EMAIL operator
• EVAL operator
• EXEC operator
• EXPAND operator
• EXPORT operator
• FOR operator
• IF ... THEN operator
• IMPORT operator
• INPUT operator
• MESSAGE operator
• MULTI operator
• NEW operator
• NESTEDSESSION operator
• NEWEXECUTOR operator
• NEWSESSION operator
• NEWTHREAD operator
• PRINT operator
• READ operator
• REQUEST operator
• RETURN operator
• SEEK operator
• SHOW operator
• TRY operator
• WHILE operator
• WRITE operator

Context independent operators

Context independent action operators cannot use external context parameters. Thus they can only be used in the ACTION statement:

• ABSTRACT operator
• INTERNAL operator
