RE: MOVE opcode in freeform (was Strange behavior w/%editc)

Funny you mention the DO(While) vs DO(Until) thing. You still see, even
today, style guides that say "Do not use Do While loops" but what the
RPG coders that assimilate this mentality don't seem to realize is, in
the language (such as Java or C) for which the "style guide" was
written, they do NOT have DOW and DOU operation codes. They have:


  Do {
    //  insert code to run here;

  }  while ( x != NULL)


So what they're talking about is that a programmer can easily miss the
fact that the above code is a DO/WHILE loop instead of a do loop.
Actually this translates to a DO UNTIL (DOU) in RPG.
