The archive file rspline.zip contains the files:
|lar13694.txt||the original program description from COSMIC|
|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.
