 Do you have a Cygwin icon on your desktop?
    If not, go to http://sources.redhat.com/cygwin and "Install Cygwin now"
       You should install, at least, Base, Devel, and Shells packages.

 Click on the Cygwin icon.  This should bring up a bash shell.
 
 Are you familiar with unix?  If not, you should find a tutorial somewhere.
    Although Cygwin is a great way for Windows users
    to access free software, it's really aimed at
    somewhat experienced unix/linux users who need to
    run on Windows.

 In your bash shell
    g77 -c fmain.f          will compile the fortran file fmain.f,
                            putting the object file in fmain.o
    g77 fmain.f -o fmain     will compile fmain.f and putting an
                             executable in fmain.exe
    g77 -c fsubr1.f
    g77 -c fsubr2.f
    g77 -c fsubr3.f
    g77 -c fcaller.f
    g77 fcaller.o fsubr1.o fsubr2.o fsubr3.o -o fprogram
                           will compile and link multiple source files.
    g77 -help gives more information.

Dear Cygwin:

Recently I purchased a HP Pavilion 750n PC, which has Windows XP, to 
perform numerical calculations at home relative to my theoretical research 
in physical chemistry.  I thought about purchasing a FORTRAN compiler but a 
friend of mine suggested that instead I download Cygwin and use the 
available FORTRAN compiler in this package of free-ware.  Well I did that 
last night, and from reading his E-mail instructions I was to download the 
g77 FORTRAN compiler.  However, it did not work on my new PC at home.  Yet, 
I only could access the g77 FORTRAN compiler in DOS via Command statement 
on RUN.  If there is instead a FORTRAN compiler already with the Cygwin and 
I was not suppose to use g77 please let me know ,and please inform me on 
how to access this Cygwin FORTRAN compiler if it exists.  I tried searching 
for any FORTRAN compiler that came with Cygwin but I could not find any 
statement on how to utilize it on the web site.  Your assistance will be 
greatly appreciated.
