The archive file contains the files:

lar13694.txt the original program description from COSMIC
readme.txt general description
ratspl.f90 the complete source code in modern Fortran
example1.f90 example program #1
example2.f90 example program #2
example1.out output from running example1
example2.out output from running example2
original.src the original copy of the source code (from COSMIC)

This is not a program, but a collection of subroutines that may be called by a driver program. Two test programs are shown to illustrate the procedures.

To run example1, first compile the sample program with the command

gfortran example1.f90 -o example1.exe

Launch the test program by typing example1.exe at the command line. There is no input file. The test program will display the output on the terminal screen.

And similarly for example2.
