property ColCount : Integer
Default: 80
Defines the number of columns across the terminal screen.
The ColCount property is the number of columns displayed by the terminal screen. For the VT100 terminal, for example, there are two possible values: 80 and 132.
If the ColCount property is changed, it is checked to be at least 2, otherwise an exception is raised.
Changing the ColCount property for an existing terminal screen does not clear the data being displayed by the screen; you will need to do this as a separate step. The positions of any horizontal tab stops are maintained, except for those that lie outside the new value for ColCount. However, any scrolling region is discarded, and the cursor is reset to the home position of the screen.
