To calculate the nuclear cross sections with a statistical and preequilibrium model as efficiently and easily as possible, a simplified- input version of ELIESE-GNASH joint program has been developed. The program has a simple input-format and a set of global optical model potential parameters. Using the present version, neutron cross sections for 25 nuclides covering the range from 27Al to 109Ag were calculated up to 20 MeV. The 50 MeV neutron induced reaction for copper, and the proton and alpha-particle induced reactions for 58Ni were also calculated. As the result of general agreements with experimental data for wide mass range, the availability of the present version of joint program is proved.
