{ Permanent | Temporary }

Permanent	A control with this style applied can be destroyed only by using the DESTROY statement or when the parent window is destroyed. A permanent control is more efficient than a "temporary" one since it is not created each time a DISPLAY statement is executed. This style is set by default.
Temporary	Temporary controls are destroyed when a DESTROY statement is executed, when the parent window is destroyed, when another control is created in its same position, or when a Screen Section containing a BLANK SCREEN keyword is displayed. Temporary controls are less efficient than "permanent" ones since they are created each time a DISPLAY statement is executed.
