TEXT:00,Here are the "dos" and "don'ts" of using element indexing in any
TEXT:16,sequence. First of all, you can replace a constant number with a variable
TEXT:16,name, like "[element_id]" for example. You can also have more than two
TEXT:16,levels of element access if the sequence is built for it. However, if an
TEXT:16,element is an atom, you cannot use another level of element indexing to
TEXT:16,go deeper into that element: only elements that are sequences can be
TEXT:16,accessed in this manner. Also, you cannot use an element number of zero,
TEXT:16,or an element number that is larger than the length of the sequence (for
TEXT:16,example, trying to access element 4 in a sequence that is only 3 elements
TEXT:16,long). 
TEXT:32,It's possible to reference more than one element of a sequence at a time.
TEXT:16,The syntax below is a variation of what you were introduced to before:
COLOUR:POINTS
TEXT:32,seq. variable   seq. variable starting element  ending element
COLOUR:EUPHORIA
TEXT:00,              =              [                ..              ]
