Description:

Given a list, apply a function to each item in the list and return the results separated by separator. Rather than walking a range from N1 to N2, this merely walks a list of supplied values. This is a recursive function. The range functions are great but sometimes you need to work with a list.

Use [n] notation to identify item in list.

applyToList( $$array ; "Case( Left( [n] ; 1)=1; [n])"; ", " )
=>
1 Adak, 10 Anchor Point, 11 Anchorage, 12 Anchorage, 13 Anchorage, 14 Anchorage, 15 Anchorage, 16 Anchorage, 17 Anchorage, 18 Anchorage, 19 Anchorage
