Hello Guilherme,
Where can I found more information about PalmOS5RE?
I read that PODS compiles ARM native code. Is it true? There is any
easy way to do that?
How can I do that?
Thanks,
Regis Melo

Hi,
When i call DmCloseDatabase, does the db
gets synced automatically or do i need to call sync explicitly (in zire

Yes, the act of closing a database does force a sync -- or at least it
does
presuming it was opened in read/write mode (and you have made
changes?).
Thanks.
DmSyncDatabase() is to allow periodic flushes
of cached information to NVFS
without the need to close and reopen the database.
Many thanks.
But what is PalmOS5RE? Does that allow you to write pnolet routines
using calls
to the various OS apis directly from the pno code? I have previously
regarded
pno code as most approriate for cpu intensive algorithms -- say
compression,
image or sound codecs, etc -- but not cases which are laden with API
calls such
as database access.
Say I have a process which must loop over all the records in some
database and
for each iteration access a bunch of other databases. Can an existing
m68k
routine be ported to a completely native pnolet routine and gain better
performance?
PalmOS5RE and Peal lets you access all(most all) palm functions in arm
mode, without having to go to 68k for that. Take a look at SuperWaba:
we got speed improvements of up to 30x when moving to it (from 68k).
