{{PageDescription}}
|
|
* {{KW|BEEP}} can be placed anywhere to alert the user that there is something to do or an error has occurred.
|
|
* [[ASCII]] control character 7 can also create a {{KW|BEEP}} sound when you {{KW|PRINT}} it (See [[CHR$]]).
|
|
* In Windows it may produce a "thunk" warning sound when a Qbasic program is running in a {{KW|SCREEN}} 0 window.
|
|
* Newer PC's may not have an internal speaker to hear ANY Qbasic [[SOUND|sounds]]!
|
|
* '''QB64''' produces the actual "beep" sound through the PC's stereo speakers.
|
|
* To produce the BEEP sound character in a QBasic(.BAS) or a batch(.BAT) file using a '''DOS''' editor (or the QB IDE) press ''Ctrl + P'' then ''G.'' PRINT it inside of quotation marks to beep in QB. Use the character after ECHO in a batch file. '''Not in the QB64 IDE!'''
