   sequences are dynamic but must be created to a given size

   or be grown by appending a value.


  Your example can be corrected in two ways

  sequence s1
  -- this creates a sequence of 10 zeros
  s1 = {0,0,0,0,0,0,0,0,0,0}
  for i=1 to 10 do
   s1[i]=i
  end for

  or

  sequence s1
  -- this creates an empty sequence and appends to it
  s1 = {}
  for i=1 to 10 do
   s1 &= i
  end for

  the reason you have an error is because Euphoria does not know
  a beginning size of your sequence.
