Palm Eudora and EudoraWeb are mostly C++. Here's a few things found.

- Exception handling adds 5Kb of object code right off the top so we don't
use it. We strive not to create lots of little allocated objects because

Seems the PalmOS 3.5 debug ROM along with 3.0a7 emulator has a very
unpleasent error response to an appropriate error check.
When (incorrectly) attempting draw operations like WinSetPattern and
FldDrawField *before* a FrmDrawForm, you get a bus error.
This doesn't seem to happen with any other
So I *think* it's safe to call DmWrite were the source and destination
overlap, but I thought I'd ask anyway. I think it's safe because my code
seems to work and because I figure DmWrite gets a semaphore, toggles the
memory protection bit and then call MemMove. MemMove is documented as safe

Just

Also don't discount the cellular telephony technologies. Many of the
problems today are economic in nature. The big carriers don't see ways to
make money with wireless data yet that really opens the service up to folks
like us, especially in this country. The big carriers are also hard to work
But, you only need a poke with a dozen bytes or two (a URL?). The device
can then bring up the higher rate data connection in a managed way.
Or said another way: we agree, the pager architecture isn't sufficient
today - it isn't the one. Ideally we'd have something that has two RF
channels; on
It's a good point, but an exception is pagers which run quite nicely on
batteries for long periods of time and receive pushes. Probably the key to
the trade-offs of battery life, through put, coverage, latency, push/pull
and cost is overall system design (servers, RF link, antenna, battery

You have two basic choices:
1) Palm VII
- possibly easier to program, might get away without C/C++
- can't transfer lots of data - only small HTTP-like requests
- have to use Palm.net
- use for web applet sort of results
2) TCP/IP
- works with lots of different services (land line modem, omnisky
Kewel, a PalmOS router! Watch out Cisco!!! :-)
But seriously, I think this is expecting too much of NetLib and probably
the serial libraries too.

Any news on where to get the fixed PalmOSGlueLib? Couldn't find it on the

use that trap.
Is there another PalmOSGlue.Lib version?
Should I be doing something else to tell PalmOSGlueLib it's running on
PalmOS 3.x?

Not sure, but can't you just take the .rsrc out of resource.frk directory
and copy it to/from the Mac?
Also, one thing that drives me nuts is the fact that the .mcp and .rsrc
files are binary and make diffs and history tracking virtually impossible.
We use Perforce for source code control and
I need to put a blob of binary bytes into a resource, 500 or so bytes -
more than you'd want to type in hex. Any ideas how this could be done? I
expect to have to do this a number of times so I want a solution that
doesn't involve typing the bytes :-). I'm using CW6 on Windows. I suppose

The way I understand it is that "save bits behind" should be thought of an
optimization and not counted on. Just so happens it works most of the time,
and if your app is very conservative with memory it will work all the time.
My only complaint is that it maybe forces me to make my app a tiny b
Probably the CharPtr should be Char *. I've found Code Warrior to produce
many misleading diagnostics of this sort.
