replist

Format: replist( list, offset, len, rep )

Arguments: [any] list Input list

[int] offset Starting location of the sublist

(int) len Length of the sublist to be replaced

[any] rep Replacement list

Returns: [any] list with len elements beginning at offset replaced by rep

Description: Replist can be used to remove, insert, or replace elements in a list.

The offset argument can be a list of integers that specify a position deep within a hierarchical list. The first integer in the list is the offset on the first level, the second element is the offset on the second level, and so on. For example, the element at offset 2 in the list [[1,2],[3,4,5],[6,7]] is the sublist [3,4,5]. The element at offset [2,3] is the number 5.

Examples: replist([3,4,5,6,7],1,1,"X") = [3,X,5,6,7]

replist([3,4,5,6,7],1,0,"X") = [3,X,4,5,6,7]

replist([[1,2],[3,4]],[1,0],1,"X") = [[1,2],[X,4]]

replist([1,2,3],1,0,["X","Y"]) = [1,X,Y,2,3]

replist([1,2,3],1,0,[["X","Y"]]) = [1,[X,Y],2,3]
