Could you refer to the following codes?
ACLS:ST$="HELLO THIS IS A TEST"
LOCATE 5,5
FOR I=0 TO LEN(ST$)-1
FOR J=0 TO 5:VSYNC 1
IF(BUTTON(0)AND #A)!=0 THEN BREAK
NEXT J
P$=MID$(ST$,I,1):?P$;
IF P$!=" " THEN BEEP 48
NEXT I
?:?
eZSB includes a method called ZTXTT which will type a string one letter at a time and make a beep in varying pitches for each letter. It's a simple implementation I added, but it works similarly to the code provided above.
