\section{Introduction}
Molecular Coding Format(MCF) is new linear notation
represent chemical structure diagrams.
This Coding is named from programing technique
such as operator, array, scope, macro, adressing, etc.
mcf2graph convert from MCF to PNG, SVG, EPS, MOL file.
It is also able to calculate molecular weight,
exact mass, molecular formula.
