The WIDTH statement changes the text dimensions of certain SCREEN modes.


Syntax

SCREEN
WIDTH [columns%][, rows%]
CONSOLE
(Windows Console Only): WIDTH [columns%][, rows%][buffer_columns%][, buffer_rows%]
File
WIDTH {file_number | device}, columnwidth%


Parameters

  • When parameters are not specified, columns defaults to 80 with 25 (30 in SCREEN 11 or 12) rows.


Description

  • WIDTH should be used after a program SCREEN statement. It does not affect screen graphics or graphic coordinates.
  • Affects SCREEN 0 Window size and alters the text block size of each screen mode listed in QBasic:
  • SCREEN 0 can use 80 or 40 columns and 25, 43 or 50 rows. Default is WIDTH 80, 25.
  • SCREEN 9 can use 80 columns and 25 or 43(not supported on many monitors) rows. Default WIDTH 80, 25 fullscreen.
  • SCREEN 10 can use 80 columns and 25 or 43 rows. Default is WIDTH 80, 25 fullscreen.
  • SCREEN 11 and 12 can use 80 columns and 30 or 60 rows. Default is WIDTH 80, 30 fullscreen.
  • QB64 can alter all SCREEN mode widths and heights which may also affect text or _FONT block sizes.
  • If a $CONSOLE window is active and you set _DEST _CONSOLE, WIDTH will affect the console output window size (Windows only), with the last two optional parameters setting the buffer size for the console. (For example, you can set a console to be 80 characters x 25 lines for the display, with a buffer size of 300 characters and 100 lines, which allows you to display that much information and navigate the visible display with the scroll bars.)
Note
WIDTH changes may change screen color settings in QBasic. Use PALETTE to reset to default colors.
WIDTH LPRINT is not supported in QB64.
