Its fine to use with the consideration that you stated above i.e. don't use it when
globals are not available.
I partition my apps into 'Entry' modules and 'Normal' modules. Entry modules have the
'#pragma exceptions off' statement in their
implementation so that I don't accidentally try to use throw, catch etc. These modules
deal with the non-global scenario launch
codes and contain any of their dependencies.
Normal modules use exceptions as you would on any other platform. I've found it
efficient to just throw Err type variables;
throwing classes bloats your code by about 5k (from what I recall).
You might want to check out my freeware C++ application framework for PalmOS (Teenee).
There are examples within Teenee of
exception handling etc.
'hope this is useful to you.
