The Template:KW statement changes the text dimensions of certain Template:KW modes.


SCREEN Syntax

WIDTH [columns%][, rows%]


CONSOLE Syntax (Windows Console Only)

WIDTH [columns%][, rows%][buffer_columns%][, buffer_rows%]

File Syntax

WIDTH {file_number | device}, columnwidth%


Template:Parameters

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


Usage:

  • 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.
