Thanks Hans;
That was what I needed. When I ran

clay@linux:/data4/C-Prog/Horton/les01 > file ex01-1
ex01-1: ELF 32-bit LSB executable, Intel 80386, version 1, dynamically linked 
(uses shared libs), not stripped

It came out as you indicted. Why did it create it as an ELF file when 
it is not one in the list of filesystems in /proc? And is there a way
to convert it to ext2 file format?
