Introducing break

[David McFarlane]

liwenna,

Thanks for a nice explanation of this alternative method.  Please 
note that the lines

if trialcounter mod 20 = 0 then
else goto skiplabel
end if

could be simplified to just

If (trialcounter mod 20) <> 0 Then Goto skiplabel

(I also added capitalization and parentheses just to suit my style).
