Quantitative Electron Probe Micro Analysis (EPMA) is carried out by non-dispersive energy analysis or EDAX or by dispersive wave length analysis or WDS. The present paper discusses a computer programme developed in BASIC language for quantitative evaluation of metallographic specimen containing a number of component elements, using the absorption, atomic number (stopping power and reflection power) and fluorescence corrections known as ZAF correction. A comprehensive flow chart and the detailed programme written in basic language are provided in the appendix which can be run in Casio PB 300 personal'computer. The programme has been tested for actual quantitative estimation of a steel specimen containing iron, chromium, manganese, carbon and silicon. The x-ray data was obtained from a Double Dispersion Spectroscope (DDS) attached to a JEOL JSM 35 CF model SEM.
