──BEEP(frequency,duration)───────
BEEP sounds the speaker at frequency (Hertz) for duration milliseconds. The frequency can be any number in the range 37 to 32767 Hertz. The duration can be any number in the range 1 to 60000 milliseconds.
This routine is most useful when called as a subroutine. A null string is returned if the routine is successful.
Here is an example:
/* C scale */
note.1 = 262 /* middle C */
note.2 = 294 /* D */
note.3 = 330 /* E */
note.4 = 349 /* F */
note.5 = 392 /* G */
note.6 = 440 /* A */
note.7 = 494 /* B */
note.8 = 524 /* C */
do i=1 to 8
call beep note.i,250 /* hold each note for */
/* one-quarter second */
end
