Scripting help

Hi,
I'm using ksh, I have a file called testfile.txt with all characters, I would like to check the file, if all are capital letter then it will return 1, if it not all capital letter then return 2.
I know i can use tr to do it, but just can't think of better way to write the script.
Appreciate any advise given.
Thanks in advance.

Hi,

What if I my text file (myFile) I have space and numeric, the above will return 1 even no small capital was found, anyway to get over space and numeric and return 0 if all capital letter regardless the file has numeric or space.
Thanks
