Palm Version

 [1/3] from: schaeper::hyperverse::com at: 23-Apr-2001 15:48


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! Tom Schaeper

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. Sterling

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. -jeff
