Thank you for the information.  The command you recommended worked, or 
at least without yielding an error message.  However, I had the same 
error message as before:

This is pdfTex, Version 3 ...
entering extended mode
(.second.tex
! Undefined control sequence.
1.5 \documentclass
    [10pt,a4paper]{article}

So, assuming that your command worked, it cannot be the line endings.
