You can't trust everything you read.

Yes, that's the original warning that I gave to the tech writer,
because the first release of PalmOSGlue.lib only contained Text Mgr
glue calls. These relied on the presence of the IntlDispatch trap to
determine whether it was safe to call the real Text Mgr routines.
Unfortunately in Palm OS 1.0 the IntlDispatch trap was actually the
PsrInit() trap, thus this check returns a false positive result, and
you'll crash & burn.
The LmGlueXXX routines are different, in that they don't test for
IntlDispatch. The specific issue is whether the 'cnty' resource
existed in 1.0. To check that, I needed to fire up a 1.0 ROM image,
which I didn't have at the time I wrote the response.
As it turns out, the 'cnty' resource was added in 2.0, so the current
documentation warning is still valid. If you call the LmGlueXXX
routines on a 1.0 ROM, you won't die, but you'll always get an
"invalid locale index" result when trying to find the index for any
locale.
