I have encountered what seems to be a bug in awk on the NeXT.
(I am using an original Cube with Version 1.0 software.)
The following awk script works correctly on Sun and Sequent
but gives the results as shown on NeXT:

#junk.awk  --- a bug demonstration
BEGIN {w=14582641; l=2754258; t=204911}
{}
END {s = w+l+t
     v = w+t+l
     print w,l,t,s,v
    }

NeXT output:
14582641 2754258 204911 17541812 17541810

Correct output:
14582641 2754258 204911 17541810 17541810

This looks like an overflow problem, but I haven't been
able to pin it down.  Does anyone know what is going on?
My confidence in using awk for grade computations is
dropping rapidly!
