256 columns (up to IV) is as far as you can go pre-2007.

16384 columns in Excel 2007:

Hi there, I am arranging some data on excel for my college course and for
some reason I cannot go further than 'IV' on the columns at the top, is
this
just the way Excel 2000 is or this there something I can do to amend this?
Thanks for reading my question and I look forward to your answers.
Many thanks,
