          INSTALLATION SUGGESTIONS FOR sppcr


The Fortran 95 source for this code is found in the files in directory
'SOURCE' that have the suffix .f90.  Fortran 95 places constraints on
the order in which routines are compiled (Fortran 77 did not).

We have provided two files to assist with compilation.

Makefile:  A make file that may be useful if your system has a 'make'
utility available.

compile.sppcr: Compilation directives as a Unix shell script.

Both files make assumptions about your machine.

(1) The  name  of  the  Fortran  95  compiler is  f90.   This  is  not
    necessarily the case.  CVF  Fortran's compiler is called f90.  Use
    a text editor to modify this as needed.

(2) The  appropriate  flags to  the  compiler  are  '-c -O'.   On  our
    machine, DEC/Compaq/Intel  Alpha running True64 Unix,  and on most
    other  Unix machines,  -c means  produce  *.o files  and -O  means
    optimize for  speed.  You may need  to adjust these  flags to suit
    your compiler.

If changes need to be made you  do not have to learn Fortran (we think
that  the Fortran that  we supply  is standard  and should  require no
changes).  You  may have to learn  to use the Fortran  compiler and to
set its flags.

Good luck.
