The program below makes the required sounds, but between each sound
there is a noticeable pause.

Why is this?  Is it possible to get a continuous sound?

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i PROGRAM
SOUNDTEST; USES    WINDOWS; VAR    I: INTEGER; BEGIN    FOR I:=30 TO
500 DO        BEEP(10*I,1000);END.
Many thanks for your help.

Because you gave it a duration. A windows.beep is supposed to be
distinguisable from a continuous sound.
So it has a slight pause.
What you you seem to want ios a sine sweep. That's rather more
complex.

That's proper code.... Although it may seem old.
