Agreed,... Here's something that may be clearer, if you haven't done so
already, (assuming *IN44 is required).

I believe you're right. However, this has the be one of the best examples
I've ever seen of something you can do in RPG that you shouldn't.

        Okay, I've got this section of code:


                    Factor1   OpCodFactor2   ResultLenDHHiLoEQ
        C                     CLEARMEMO
        C           CM        COMP 'CM'                     44 On if CM='CM'
        C  N44      CM        COMP 'DM'                     44 On if CM='DM'
        C   44      CM        IFEQ 'CM'
        C                     MOVEL'* CREDIT'MEMO    8
        C                     MOVE *BLANKS   PONO
        C                     ELSE
        C                     MOVE *BLANKS   PONO
        C                     MOVEL'*  DEBIT'MEMO    8
        C                     END


        Here's my question - My first thought was that this might be a
coding
        error - that if CM was set to 'CM', Memo would contain '* CREDIT'
and PONO
        would be blank, and if CM contained anything else, MEMO would
contain '*
        DEBIT' and PONO would be blank.

        Then, I realized (I THINK) that the whole IFEQ stmt only is
processed if CM
        equals 'DM' or 'CM' - anything else and the IF stmt is bypassed,
right?  So,
        if CM was blank, MEMO would be blank too, correct?

        Hope this makes sense...
