Re: CF-Spec - another call for opinions

["Denis Robitaille" <DRobitaille@xxxxxxxxxxxx>]

There was a similar looping mecanism in LISP. I really like your idea. In my 
whish list, it is defined like this:

LoopBegin
{some code} (0,1 or more statements)
LoopCondition {Booleean expression}
{some code} (0,1 or more statement)
LoopEnd

When the loop condition is false, we go to the statement after the LoopEnd

On a slightly different subject, your example reminds me of a wish list item
I have.  Many many moons ago when I was programming in Forth, we had a
Begin..While..Repeat loop.  This loop would solve the age old question of do
you use 2 Reads or an If inside the loop when looping thru a files records.
For example:

2 Reads method:

      CF read MasterFile
      CF dow Not %eof
      CF    (loop processing code)
      CF    read MasterFile
      CF enddo

If inside loop method

      CF dou %eof
      CF    read MasterFile
      CF    If  Not %eof
      CF        (loop processing code)
      CF    endif
      CF enddo
or
      CF dou %eof
      CF    read MasterFile
      CF    If  %eof
      CF        Leave
      CF    endif
      CF    (loop processing code)
      CF enddo

Begin..While..Repeat

      CF Begin
      CF    read MasterFile
      CF While Not %eof
      CF    (loop processing code)
      CF Repeat

The Repeat causes a jump back to the Begin.  If the While is false,
execution goes to after the Repeat.  Note that any code can go between the
Begin and While and it always executed at least once.  I really liked this
construct when I had it, don't know how receptive others would be to it.

Thanks for asking and listening!
Rick
