After ninety years of research, the Indus Script still remains un-deciphered. It is because of non-discovery of any bilingual or multi-lingual inscriptions like Rosetta Stone in the case of Egyptian hieroglyphics. This handicap is being slowly overcome by the analytical methods that can be used in the computational research of the Indus Script. I have recently developed a software program to analyse the signs and inscriptions of Indus Script. The program helps one to formulate concordance tables for any pre-assigned combination of signs. Thousands of such concordance tables can be generated by the computer program on the fly. Some of such tables are offered to the other research scholars in several collections. This is the first collection in the series.
