(Using EXCEL 2003) version 11+

I have a worksheet setup and using a number of fixed lengthed columns across
the worksheet. I've entered my data in the columns. Now below the last
entries, I want to type a sentence beginning in column A and expecting it to
span across adjacent columns (B, C, D, whatever it takes.) When I do that,
starting in colum A, the sentence fills in just Column A and word wraps. I
don't want this. How can I get EXCEL to do what I want?
