Subject: DmWrite() is not writing the correct string???

In my app, i have to save a list of SMS msgs. I am simply putting them in a
DB with a ":" between each one. This way i can copy it to a string, replace
the : with a NULL and have a string ready to send to a list. This ofcourse
works fine in my app when the app is running. But there is a 2nd place I do
the same thing, and its from a launch code that deals with a SMS msg coming
into the device. The problem is that on the DmWrite() call that is putting
the ":" in place, it puts some y with dots over it???? if i try a ";" same
thing, but if i try anything thing else, like "-" it works fine. Im lost on
why this is going on. Ofcourse I can simply change the char that I use to
split up the SMS msgs, but Im still amazed at what its doing.
If you look at the Palm OS character set you'll find the "y with umlaut" is 255 (or-1)
and is also what is contained in the area of memory pointed to by NULL.
Therefore you are copying from a NULL pointer.
Which probably means you are calling some function that returns NULL, and you aren't trapping the error.
By the way, you are ensuring the SMS messages don't already contain colon aren't you ?
