[REBOL] Re: Palm Version

[sterling]

Whoa!  Slow down on the messages.  I've received this one 4 times now.

Anyway, a Palm/OS version is not anticipated any time soon.  The
memory architecture of Palm/OS is very limited, not just in space, but 
in the amount of dynamic memory available at boot time.  Right now, it 
just isn't anywhere near enough to get REBOL running.

If the memory restrictions go away or the system changes in the future 
to allow a port then we will certainly revisit it.

 Hi,
 
 I am new to the Rebol list though I have been following the progress of Rebol for a 
while. I was wondering if their is a Palm/OS version of Rebol anticipated.
 
 Thanks for all your input!

Hi, Tom,
You may have figured out that there is a 15-20 minute delay in the relaying
of posts:-)

Here is an excerpt from a message a couple weeks ago:
From Jeff on 11-Apr-2001:

  Yes, the REBOL Palm port lives in a border town next to the
  realm of possibility.  REBOL has even been compiled for
  Palm before, but the problem is that in order for REBOL to
  run (or even to boot) a segmentation paging scheme (virtual
  memory) has to be used.  Under such a scheme, page faults
  would occur constantly.  More time would be spent moving
  memory than in being an interpreter. As you approach the
  problem of a REBOL Palm port, it becomes increasingly
  infeasible.

  The other approach is to hack the memory protection of Palm
  OS.  This isn't acceptable, though, because of the potential
  for accidentally hurting other apps or data on the pda.

  There's still more issues, from Palm's event model and how
  REBOL's works, potentially workable, but still an issue.

  And how do you write scripts -- in graffiti?? Storing and
  load scripts from the database?

  Anyhow, there were enough demonstrable problems with it that
  we scrapped consideration of the Palm -- to the
  disappointment of many.
