Considering the fact that I write for a living, I really didn't express
myself very well, James.  I apologize.  In one of your prior posts you
said:

This implied that you considered extended factor two somehow "above and
beyond" standard fixed format RPG IV.  My point was that most of the
things you included as benefits of /free are indeed available in fixed
format RPG IV.  The extended factor two is what makes /free so
superfluous.

Yes, but for more than just the fact that it is unnecessary.  I also
dislike the fact that it makes your code "modal", and in the /free mode,
some normal operations like MOVE no longer work, or work differently.
The decision by the compiler team to remove functionality in order make
use of the /free syntax is the primary object of my concern.

You miss the point - it is the loss of the MOVE operation, and the fact
that mathematical operations no longer work the same, and the loss of
syntax checking, and the unnecessary requirements for semicolons - it is
these things that make /free an onerous change.  Where a simple
extension to the fixed format could have made for a seamless change, the
compiler team instead made it unnecessarily difficult to move from one
syntax to the other, and it is that with which I disagree.

It is not that /free is bad.  It is just that its benefits do not make
up for the things the compiler team decided we must lose to get there.
And it's especially distasteful because there are no sound reasons for
the losses.

No, but the errors in your assumptions undermine the credibility of your
statements.
