You could store the record as XML, then you could have records with

If XML is too much overhead, then just store them as packed strings with a
one byte attribute at the head of each string and #define the attribute/byte

1) 3 second delay --- use SysTaskDelay so the OS can do some work - that
will probably do it.
2) other though if #1 doesn't do it, you have your linger (remain open) set

I'd linger less or sleep more (

Looking at the PalmOS source code, it does free "dynamic" UI elements. Other
than field memory, all memory in a form exists within one allocated handle.
When you add elements, that handle is resized. When you delete the form, the
single handle is freed (after any field memory is freed.)
OS Source
If you're changing the memory associated with a field (via FldFreeMemory())
it does not update the selection. Just set the selection to none via:
FldSetSelection (fldP, 0, 0); // select none
before you free or change the field's associated memory.

Not really... you've got two choices -- you can switch to another app
(SysUIAppSwitch), essentially exiting your app, or you can sublaunch another
app (SysAppLaunch) and pass it a specific launch code. In the latter case
the app you sublaunch must be coded such that it handles the launch code in

You can request that the data be sent uncompressed. Do this before you issue
the request:
DWord conv = ctpConvNone;
// turn off compression
INetLibSettingSet (ilibRefNum, inetH, inetSettingConvAlgorithm, &conv,
sizeof(conv));
