Form Property - Call Operation (Magic xpa 2.x)

The Form property is optional and shows the Identification number of a form in the calling task. If you leave the default setting, which is 0, then the Main window of the called task will appear in its own window. If you specify a number in this property, then the corresponding form will be used as the window to contain the called task's Main window. That is, when the called subtask or program starts running, its Main window will appear inside of the window specified by the Form property.

You can zoom to select a form from the Form List.

The form specified in this property must be defined as Class 0, and can be whatever size and position you like. Do not define any text or variables in this window.

When you use the Returned Context ID property, the Form property will be ignored.
