Conversion of small letters to capital letters

Conversion of small letters to capital letters

This is my first assembly language class and I'm completely confused.  Could someone help me in writing a program to convert small letters to capital letters?  I'm hoping that seeing the actual code will get me over this initial point and help me get on with attempting to write more code.  Thanks for any help you can give me.

Try AND AL, 0DFh.

RE: Conversion of small letters to capital letters

Better filter out the input first - check if it's between 97 and 122 (inclusive) so that you're sure it really is a small letter.  If it isn't between those values, don't pass it through the and al,0dfh.
