Re: Suggested technique

Hi Alan.  Thanks again for the tip.  

I always grapple with the idea of not using iter and leave also.  I
don't see how it makes the code clearer to the reader, by eliminating
these ops.  I took your example, and eliminated the iter, as follows:


Dou iSay;
    iSay=*On;
   
    // Find next memo seq# for member
    SetGT(E)  (CI.Family#:CI.Member#) Mmemo_I;
    ReadPE(E) (CI.Family#:CI.Member#) Mmemo_I MI;
 
    If %Found(Mmemo_I);
       MO.Mmseq#=MI.Mmseq#+1;
    Else;
       MO.Mmseq#=1;
    EndIf;

    Monitor;
            Write Mmorec MO;

            On-Error *File;
               iSay=*Off;
    EndMon;
EndDo;

Now this is a very simple loop, and doesn't even transcend a page, but
in general, while perusing the code, you have to look to the beginning
of the loop to determine the condition of the loop.  If using iter,
you also have to peruse to the top of the loop anyways, so what's the
diff?
