Perhaps add the number to the index within the list, so you can skip backwards or more than one item forward. The loop ends whenever the index is out of bounds.

STEP with positive or negative argument would be coherent.
FOREACH could also be a good keyword for this.

Another point… I Always like the way Pascal does with ordered set, and allows things like :

If MyVar in [ 1 .. 4, 7, 10, 15 .. 20 ] Then ….
If MyVar in [ 'a' .. 'z' ]

But Pascal is a strongly typed langage.
