The Frame Connect To (Magic xpa 3.x)
Each frame can then be connected to a Program, Subtask, or Form. This works very much the same as it does for subforms. You can use Arguments and Automatic Refresh.
The Form type is used when you want to display data from the current task, without calling a subtask.
You must choose something to display in each frame. If you want to change what is displayed in the frame at runtime, create a blank or "dummy" task that will display when nothing else is called.
