Usage:

 

BEEP generates a sound through your computer's speaker. You can use it in batch files to signal that an operation has been completed, or that the computer needs attention.

 

Because 64-bit versions of Windows do not support playing sounds through the Windows Beep API, TCC x64 uses DirectSound for BEEP.

 

Because BEEP allows you to specify the frequency and duration of the sound, you can also use it to play simple music or to create different kinds of signals for the user.

 

You can include as many frequency and duration pairs as you wish. No sound will be generated for frequencies less than 20 Hz, allowing you to use BEEP as a way to create short delays. The default value for frequency is 440 Hz; the default value for duration is 2.

 

Numeric input may be entered in either decimal format (a sequence of 0-9 digits) or in hexadecimal format ("0x" followed by a sequence of 0-F hex digits).

 

This batch file fragment runs a program called DEMO, then plays a few notes and waits for you to press a key:

beep 440 4  600 2  1040 6

pause Finished with the demo - hit a key...
