Actually, I was little surprised that variable test2  was  processed in 
this if/else control  structure.

on mouseup
  if 1=2 then
      put 1 into atest
  end if
   if atest is an integer then beep
end mouseup

no beep of course

I expected  the similar behavior in example with  arrays.

Additionally, what  bothered me  is that if variable test2  WAS executed
then why put key() returned  empty and  not it's value = 1 as in Andu's example


on mouseUp
    put  1 into test2
    put 55 into  GrandTotals[test1]
    put 66 into GrandTotals[test2]
    put 22 into  GrandTotals[test3]
end if
  
  put keys (GrandTotals)
  
  -- returns
  --
  1
  test1
  test3
  -
end mouseUp
