Consider the following examples.

;; find the number of file name segments

SET filename = "data.temporary.sbc.xml"

;; find how many "." occur

SETSUBSTR dots = filename "."

;; dots will be equal to 3 (segments equals dots + 1)

;; determine if file name has an extension

SETSUBSTR dots = filename "."

IFNUM= dots 0 goto no_extension
