DECLARE FUNCTION WordS% (TempLine AS STRING)
DECLARE FUNCTION WordN$ (TempLine AS STRING, num AS INTEGER)

REM WordS%
REM Returns the number of words in a string

REM WordN$
REM Returns a specific word in a string

REM Both funtions treat quoted words or frases as one word

REM These functions are in AREXX the Amiga version of REXX.
REM I found them usefull and used then alot. When is started useing
REM basic more I found i needed to write theses funtions to make string
REM prossesing a little more easier.
