Hmmmm - that says that "ABC DEF" is not uppercase (because of the space in 
the middle).


function isUpperCase pText
   set caseSensitive to true
   return (pText = upper(pText))
end isUpperCase

Not that that's perfect either - the problem is there are 4 (or 5) possible 
results
   upper case
   lower case
   word case
   mixed case
   no case (i.e. no letters)
so deciding just which ones to include as "isUpperCase" is a 
context-dependent choice.
