yes , you are - George talked about delimited list as "item1,item2,item3"
but you can still use a for loop
do something like :

LPARAMETER tcString
* tcString is strings like "item1,item2,item3"
LOCAL lcString,lnNumOccurances,lnI,lnPos

lcString=tcString+"," 
lnNumOccurances=LEN(lcString)-LEN(STRTRAN(lcString,","))

FOR lnI=1 to lnNumOccurances
    lnPos=AT(",",lcString,1)
    * you can do whatever instead of printing 
    ? LEFT(LEFT(lcString,lnPos-1)
    lcString=RIGHT(lcString,len(lcString)-lnPos)
ENDFOR
