I am trying to read a PICT resource into my application.  I have a if-then
statment which checks to see if the resource really existed, but it never 
gets called in the error case.

The code is:

var pict : picHandle;

pict := PicHandle(Get1Resource('PICT',pictNumber));
if ResError = noErr then
    { do something}
else
    { handle error }

Well, i went in and found out that ResError ALWAYS returns noErr. What's up?
I assume that Get1Resource works error handling like GetResource since it
doesn't say otherwise. I tried making pictNumber a value i knew corresponded 
to a given PICT and then a value i knew didn't exist.  Both had noErr for
ResError.

Confusedly,
