The process flowsheet simulator FLOWTRAN was converted from FORTRAN 77 code to FORTRAN 66 code. The conversion was accomplished by developing a number of subprograms to handle FORTRAN 77 intrinsic functions that are missing in the FORTRAN 66 standard and by altering the code to take advantage of the developed subprograms. Also developed were a set of procedure files for executing the FORTRAN 66 FLOWTRAN on a Sperry-Univac 90/80-4. The new FLOWTRAN was tested and performs identically to the FORTRAN 77 version. The FORTRAN 66 FLOWTRAN can be installed on any mainframe computer with a FORTRAN 66 compiler.
