Purpose With FieldSize you can change the size of an input or output field.
Examples

Further examples 		FieldSize F[Material] 10
Format FieldSize [Screen element] n

The new field size is n characters; is a value between 1 and the current field size.
Options
-scrollable Only that part of the input field which is visible is reduced; the field becomes scrollable and can still be made the same length as it originally was.
Hints
  • If the value to be used has more than n characters, the field becomes scrollable automatically, so that the user can display the increased value. But normally FieldSize should be used only if you are sure that the field value will not be more than n characters long, or if its use is combined with the -scrollable option.
