# PLAY() ## Effect Checks if music is being played via PSG channels. The function returns -1 (true) if the selected channel is playing. If playing has ended the function returns 0 (false) again. If the function is called immediately after the `PLAY` statement the value -1 is persistent. ## Syntax `PLAY(<Channel>)` ## Parameter `<Channel>` allows to specify the PSG channel(s) to check: - 0 = all channels - 1 = channel 1 - 2 = channel 2 - 3 = channel 3 ## Examples ```basic 10 PLAY "CDE" 20 IF PLAY(0) THEN 20 ' Wait for playing to end on all channels ``` ```basic 10 A$="":BEEP 20 FOR I=1 TO 6 30 READ AA$:A$=A$+AA$ 40 NEXT I 50 PLAY "XA$;" 60 SCREEN 0:CLS 70 IF PLAY(0)=-1 THEN PRINT "The music is playing":GOTO 70 80 PRINT "The music has ended" 90 END 100 DATA CCGGAAGR 110 DATA FFEEDDCR 120 DATA GGFFEEDR 130 DATA GGFFEEDR 140 DATA CCGGAAGR 150 DATA FFEEDDCR ``` ## Related to `BEEP`, `CALL PLAY`, `PLAY` ## Compatibility MSX-BASIC 1.0 or higher ## Source Retrieved from "https://www.msx.org/wiki/PLAY()"
