Script Command: BEEP
BEEP [{frequency (hz)} {duration (msecs)}]
This command simply provides the script writer with the ability to alert the user with some basic (i.e. annoying) single-frequency tone. If no arguments are specified, the frequency defaults to 500Hz and duration is 250 milliseconds.
Note: if you wanna alert the user, also consider the CLS command's ability to change the font and background color, or use SYSTEM to play a .WAV file.
