EXECUTE METHOD


EXECUTE METHOD ( methodName {; result {; param}}{; param2 ; ... ; paramN} )

Parameter	Type	Description
methodName	String	Name of project method to be executed
result	Variable, Operator	Variable receiving the method result or * for a method not returning a result
param	Expression	Parameter(s) of the method

Description

The EXECUTE METHOD command executes the methodName project method while passing any parameters in param1...paramN. You can pass the name of any method that can be called from the database or the component executing the command.

In result, you can pass a variable which will receive the result of the execution of methodName (value placed in $0 inside methodName). If the method does not return a result, pass * as the second parameter. If the method does not return a result and does not require any parameters to be passed, pass only the methodName parameter.

The execution context is preserved in the called method, which means that the current form and any current form event remain defined.

If you call this command from a component and pass a method name belonging to the host database in methodName (or vice versa), the method must have been shared (“Shared by components and host database” option, in the Method properties).

System variables and sets

If this command is executed correctly, the system variable OK is set to 1; otherwise, it is set to 0.
