Valid values for columns are 80 and 132; for rows, use 25 or 50. (Do not include the brackets.)

For example, if you want your screen to display 132 columns and

25 rows, type the following and press Enter:

VGAMODE 132, 25

To use VGAMODE, you must configure the application program that uses VGAMODE for the same screen size. See the appropriate section in this appendix for your application program(s).

Note

Certain monitors cannot display 132 columns or 50 rows on the screen. The following table specifies the number of rows that can be displayed on common monitors:
