The original CINDA computer program, coded in FORTRAN-II and FAP for the IBM-7094 computers, is documented as Chrysler Corporation Space Division Technical Note TN-AP-66-15, dated April 30, 1966.It has gained wide acceptance and usage through- out the Thermodynamic community and in fact become a standardized program at several installations.However, the original program was unsuitable for standard operation on third generation computers.Therefore, the National Aeronautics and Space Administration's Manned Spacecraft Center awarded a contract to Chrysler to produce the version described herein.This new version entitled CINDA-3G is coded in FORTRAN V for the Univac-1108 computer.Minor portions are coded in the Sleuth II assembly language in order to achieve bit manipulation and shifting operations where required and also to allow certain user subroutines to have a variable number of arguments.Problem data decks prepared for the old version require only a few changes in order to run under the new version.Although numerous comparisons will be made to TN-AP-66-15, this document is intended to be complete and self-contained.
