; TEST4.ASM by Warren A. Ring
;
; This program shows an example of how words can be extracted from a
; phrase. This program allows you to enter a phrase, then it displays
; the individual words from that phrase. Note that this example, which
; uses the "Scana" routine, treats all non-alpha-numeric characters as
; delimiters. Thus, it skips over commas, semicolons, and other special
; characters just as if they were spaces.
