Oops,  

Before anyone catches my mistake.  I did modify the original file so the
echo statement would reference my file equation.

Here's the corrected command file.

        setvar count 0
        #echo 1 > myfile
        input count <myfile
        setvar count !count+1
        echo !count >*myfile
