When you do your comparison, use the == operator to do an exactly equals. And if you need to test for not equals, use "NOT x == y".

I do something similar in one of my processes.

VarString= "Var2=cd, Var3=ef, Var4=gh, Var5=ij, Var6=kl, Var7=mn, Var8=op, Var9=qr, Var10=st"

DIMENSION laLines[1]
ALINES(laLines, VarString, 2 + 4, ",")
FOR lnI = 1 TO ALEN(laLines, 1)
    * Grab the components
    lcVarName = ALLTRIM(GETWORDNUM(laLines[lnI], 1, "="))
    lcValue   = ALLTRIM(GETWORDNUM(laLines[lnI], 2, "="))

    * Process here
    ? lcVarName, lcValue
NEXT

It will give you the breakout of each item in a comma-separated list like that. And if you have the data in some other way, you can adjust the parse character in ALINES(), or use another method to break out the lines.
