For/endfor loop

This bothered me all night.  In a recent discussion about printing a subfile
Scott mentioned using a for/endfor loop instead of the dow loop.  No one
commented on it.

If I understand correctly the for/endfor loop would do the following:

If we define SFLRECS as SFLSIZE(&SFLRECS) and wCount as like(SFLRECS) then
the for loop looks like this:

  C                   for       wCount = 1 to SFLRECS
  C  wCount   chain   SFL
  C                   exsr    PrintLine
  C                  endfor

 This is all that is needed.  No priming chain or read, no need to set
wCount to 1, no need to increment wCount, and no need to worry about %eof.

This is much leaner, clearer, and intuitive to my mind.   

That is, if I have understood what he said correctly???
