The INVOKE command invokes a method. A method can be a standard method such as a form's Show and Hide methods, or it can be a user-defined method.
Custom-defined methods can also accept input values and can return output values. When you invoke a method like this you need to pass a value and assign a field for the returned value.
Methods are often used by an owner form to instruct a member form to perform some action. Note that a component can also invoke its own methods, for example a form can close itself by invoking its Hide method.
The specification of the INVOKE command is as follows:
INVOKE Method(method_expression) ParmOne(#ArgOne) ParmTwo(#ArgTwo)
Using RDMLX, without its name, the command can be entered in the following way:
method_expression ParmOne(#ArgOne) ParmTwo(#ArgTwo)
