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


Syntax

For SCREEN
  • WIDTH [columns%] [,rows%]
For CONSOLE (Windows Console Only)
  • WIDTH [columns%] [,rows%] [,buffer_columns%] [,buffer_rows%]
For 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.


Examples

$CONSOLE:ONLY
WIDTH 80, 25, 300, 100
CLS
FOR i = 1 TO 97
    PRINT i
NEXT
PRINT STRING$(100, "0") + STRING$(100, "1") + STRING$(100, "2") 'print the 100's placeholders
FOR j = 1 TO 3
    FOR i = 0 TO 9
        PRINT STRING$(10, _TRIM$(STR$(i))); 'print the 10's placeholders
    NEXT
NEXT

FOR j = 1 TO 30
    FOR i = 0 TO 9
        PRINT _TRIM$(STR$(i)); 'print the 1's placeholders.
    NEXT
NEXT
