You do not need to use a Mathematica notebook to run FeynCalc code.
You can find some old ASCII-only examples in the original FeynCalc Guide (get all FCGuide*.ps.gz files) at
http://www.feyncalc.org/oldfc/

What you want is not possible at all.

MathCode will not do what you want.
It is easy to find in :
