High Energy Transport Code (HETC) based on the intranuclear-cascade-evaporation model is modified for calculating the proton-induced fragmentation cross sections. The systematics of the fragmentation reaction are empirically formulated using the excitation energy after the cascade collision. The systematics are incorporated into the HETC as a subroutine set. The free-space nucleon-nucleon collision cross sections in the HETC were replaced by the in-medium ones. The fragmentation cross sections by the modified HETC (HETC-FRG) are compared with the results by other codes based on the intranuclear-cascade-evaporation model. It is shown that the HETC-FRG reproduces experimental data particularly on emission of fragments such as <SUP>7</SUP>Be typically within an accuracy of a factor of 2.
