$CONSOLE
The $CONSOLE Metacommand creates a console window that can be used throughout a QB64 program module.
Syntax
- $CONSOLE[:ONLY]
- _CONSOLE ON or OFF may be used to show or hide the console window at run time.
- The :ONLY option can be used when only a console window is desired without a program window.
- _DEST _CONSOLE may be used to send screen output to the console window.
- _SCREENHIDE and _SCREENSHOW can be used to hide or show the main program window.
- _DELAY or SLEEP can be used to allow the console window to be set in front of the main program window.
- QB64 Metacommands are not commented out with ' or REM, differently from Qbasic metacommands
- Change the title of the $CONSOLE windows created using _CONSOLETITLE
- Note: Text can be copied partially or totally from console screens in Windows by highlighting and using the title bar menu.
- To copy console text output, right click the title bar and select Edit for Mark to highlight and repeat to Copy
Examples
Example 1: Hiding and displaying a console window. Use _DELAY to place console in front of main program window.
$CONSOLE _DELAY 4 _CONSOLE OFF _DELAY 4 _CONSOLE ON _DEST _CONSOLE PRINT "Close this console window or click main window and press a key!"
Example 2: How to use a Console window to copy screen output using the Edit menu by right clicking the console title bar.
$CONSOLE _DEST _CONSOLE c&& = -1: d& = -1: e% = -1: f%% = -1 hx$ = HEX$(f%%) PRINT "Max hex _BYTE = "; hx$; " with"; LEN(hx$); "digits ="; VAL("&H" + hx$) hx$ = HEX$(e%) PRINT "Max hex INTEGER = "; hx$; " with"; LEN(hx$); "digits ="; VAL("&H" + hx$) hx$ = HEX$(d&) PRINT "Max hex LONG = "; hx$; " with"; LEN(hx$); "digits ="; VAL("&H" + hx$) hx$ = HEX$(c&&) PRINT "Max hex _INTEGER64 = "; hx$; " with"; LEN(hx$); "digits ="; VAL("&H" + hx$) hx$ = HEX$(9223372036854775807) PRINT "Max _INTEGER64 value = "; hx$; " with"; LEN(hx$); "digits" hx$ = HEX$(-9223372036854775808) PRINT "Min _INTEGER64 value = "; hx$; " with"; LEN(hx$); "digits"
Max hex _BYTE = FF with 2 digits = 255 Max hex INTEGER = FFFF with 4 digits = 65535 Max hex LONG = FFFFFFFF with 8 digits = 4294967295 Max hex _INTEGER64 = FFFFFFFFFFFFFFFF with 16 digits =-1 Max _INTEGER64 value = 7FFFFFFFFFFFFFFF with 16 digits Min _INTEGER64 value = 8000000000000000 with 16 digits
- Console: Right click and select Edit > Select All (mouse highlight after) then hit Enter or select Edit > Copy to the clipboard.
Max hex _BYTE = FF with 2 digits = 255 Max hex INTEGER = FFFF with 4 digits = 65535 Max hex LONG = FFFFFFFF with 8 digits = 4294967295 Max hex _INTEGER64 = FFFFFFFFFFFFFFFF with 16 digits =-1
- Copied text: The above text was copied after Select All was selected and the smaller area was re-highlighted with the mouse.
