The archive file contains the files:

lew13854.txt the program description from COSMIC
readme.txt general description
original.src the original copy of the source code (from COSMIC)
cas2d.f the complete source code in modern Fortran

To compile this program for your machine, use the command:

gfortran cas2d.f90 -o cas2d.exe

Linux and Macintosh users may prefer to omit the .exe on the file name.

To launch the program, enter "cas2d" at the command line. This old program uses a legacy style of assuming the input is from standard input and output to standard output.

cas2d < mycase.inp ^gt; mycase.out

There seems to some residual problem with this code. Even though it runs and produces satisfactory answers, it always gives warnings of invalid floating point operations, namely a denormal flag. I will continue to investigate, but I want to release it because some of you may well be better at diagnostics than I am.
