Great! The only reason I mentioned it is that I personally think that most folks in general don't know how they can save themselves code and aggravation by modifying the way they handle logical values. For example, how many times have we seen some of the following:

IF lcondition = .T.
  * Just IF lcondition suffices
  * This adds size because of the literal use of .T.
ENDIF
* Or
DO WHILE .T.
  * Same as above, plus
  IF lSomeConditionalExpression
    * Addtional pcode for the second evalution
    * and the EXIT statement
    EXIT
  ENDIF
ENDDO
* Rather than
ldone = .F.
DO WHILE NOT ldone
  ldone = lSomeConditionalExpression
ENDDO

But that's just me.:-)
