i also like the nokia ring tone player MicroMusicWithRtttl.bs2 from Wamv2_2.pdf. lot's of ringtones on the web.

RTTTL_File DATA "simpsons:d=4,o=5,b=160:c6,e6,f#6,8a6,g6,e6,c6,8a,8f#,8f#,8f#,2g,8p,8p,8f#,8f#,8f#,8g,a#,8c6,8c6,8c6,c6"

Dave,

I can get the program you posted "piezo pal.bs2" to run, but I have some questions about its code. The last code part is as follows:


SHOW4: DEBUG "Heart and Soul",CR

LOOP 'Get the next note to be played

Song4
LOOKUP indx,[noparse][[/noparse] C5, R, C5, R, C5, R, C5,BE4, A4,BE4, C5, D5,R, C5, E5, R, E5, R, E5,0],note
LOOKUP indx,[noparse][[/noparse]450,50,400,50,750,90,200,300,200,300,200,300,5,200,450,30,450,50,800],dura
IF note = 0 THEN DELAY 'it.
IF note = R THEN REST
FREQOUT 4,dura,note
NXT
indx = indx + 1
GOTO LOOP
REST
PAUSE dura
GOTO NXT

DELAY
note = 0
dura = 0
indx = 0
PAUSE 200
STOP

There is not a colon ([noparse]:)[/noparse] after the "labels" nxt, rest & delay. I thought you had to have a colon after labels? This works ptogram runs, but is it just not "good" coding? Your comments about how this code is written would help me in my own coding.

"Good" coding suggests using colons after labels, and when using version 2.5 syntax in the BASIC Stamp IDE colons after labels are required.
