- I debated whether to mention the BY 1 or not. It is there for PL1
- compatibility (I used to write a lot of PL1). In PL1, DO I=1; means
- the same as DO I=1 TO 1; so you really need the BY 1. Of course, in
- REXX it is optional, but it does reinforce the idea that we wish to
- step thru I values without limit (while TO something just implies that
- there is this magic value something that is our upper limit). Good
- point. Dave
