6.13.3 Form's Position
Use the FormPosition property to specify the size and the position of the form at run-time. Any changes you make to the FormPosition values are only visible at run-time.
You can specify that at run-time the form has the same position and size as at design time (Designed), that it is centered or that it uses default position and/or size. The default size and position of new forms is specified in the #STD_FORM component which you can modify.
