**PROP:NoHeight** is a toggle attribute which returns whether the window or control was set to default its height (had an omitted height parameter in its AT attribute). Setting this property to TRUE is equivalent to resetting the control to its default height as determined by the library (which you cannot do using PROP:Height).

**PROP:NoWidth** is a toggle attribute which returns whether the window or control was set to default its width (had an omitted width parameter in its AT attribute). Setting this property to TRUE is equivalent to resetting the control to its default width as determined by the library (which you cannot do using PROP:Width).

**Example:**

**WinView   WINDOW('View'),AT(0,0,,),MDI,MAX,HVSCROLL,SYSTEM,RESIZE**

**        LIST,AT(6,6,120,90),USE(?List),FORMAT('120L'),FROM(Q),IMM**

**      END**

** CODE**

** OPEN(WinView)**

** IF WinView{PROP:NoHeight} = TRUE**

**  WinView{PROP:Height} = 200          !Set height**

** END**

** IF WinView{PROP:NoWidth} = TRUE**

**  WinView{PROP:Width} = 320          !Set width**

** END  **

** ACCEPT**

** END**
