Strange POSITION> Function Behavior

[Waldo]

I've used several other program languages but have NEVER seen the behavior shown by the POSITION> command while searching for substrings when the search is initiated from other than the first character.

EXAMPLE:
let>string=ABCDxxxEFG
Pos>xxx,string,4,ptr

Most other programs would return 5 as the resultant pointer (ptr).
Macro Scheduler returns a 2

Every other programming language I've used returns the pointer in absolute terms related to the original string. Macro Scheduler apparently returns the pointer relative to a substring beginning at the start-search index.

This is crazy behavior, if not an outright bug.
At the very least, the documentation should reflect the operation.
