API's & upper vs. lower case

Hi,
I am using prototypes that serve as wrapper functions to call
QCMDEXC, QUSROBJD, QSNDDTAQ and QRCVDTAQ  in an
application that utilizes data queues.  The name of the data queue
that I am using is "PLATES".  Well, on a number of occasions,
I have mistyped  "PLATES", and instead types "Plates".

Well it seems that when I check for the existence of the object
using QUSROBJD, and "PLATES" already exists, but I specify
"Plates"  instead, I get CPF9801 = obj not found. 
So I go and create the DTAQ "Plates" using QCMDEXC and CRTDTAQ,
and that blows up because "PLATES" already exists.
Well if it already exists, then why wasn't it found on the QUSROBJD call?
When I fix my typing errors, its works as expected.

I've encountered similar errors when I use "Plates" on the
QSNDDTAQ rather then "PLATES".   I am told then that the
DTAQ doesn't exist.

FYI: My prototypes use the CONST keyword whenever passing
       the DTAQ name.

The problem is (obviously) easy enough to fix, but, how come 
this sort of behavior exists?  Does OS/400 know the difference between
the DTAQs "PLATES" and "Plates"?  Is it the API's making the
distinction?  Something with my prototypes?

I appreciate any clarity that you can offer.
TIA,
Dave
