I have some new info. 

Some of you have sent me some suggestions but none solved my problem.
I have used 'echo $PATH' to check my PATH environment variable and
there is a ':' at the beginning of the path.  So that isn't it.
Also, I entered './a.out' to make sure I'm running the right a.out
file and I get a upgrade of the old error message: './a.out: Cannot execute'

I have also transfered the a.out file to another 3b2 via floppy disk
and it executed fine on that machine so I know programs compile properly
on my 3b2 and therefore, the magic numbers, etc. exist and are correct
in the a.out files.

Could there be a transparent security code in the propriety chips that is
causing the problem?  I wasn't around when the ATT service personnel fixed
the 3b2 after its hard disk crash but someone told me that he didn't
change any of the boards - he just changed some chips on the boards.
Could that be the problem?

If anyone has anymore suggestions, please mail them to me as soon as possible
because I would like to get this 'unsurmountable' problem resolved.
