Subject: Using the Sun Fortran Compiler on the CSLab System


I mentioned in class that you should use the Sun f77 compiler on the
CSLab system to do the assignments for CSC 2307.  To ensure that you
get this compiler on the CSLab system, you should modify your .cshrc
file as follows.

Find the section of your .cshrc file that looks like:

        if ( -r /slocal/etc/site.cshrc ) then
                source /slocal/etc/site.cshrc
                set path=($path .)

add the line:
                setenv SUNWspro yes

to make it look like:

        if ( -r /slocal/etc/site.cshrc ) then
                setenv SUNWspro yes
                source /slocal/etc/site.cshrc
                set path=($path .)

Then login to either a CSLab Sun workstation or one of the CSLab
Sun servers (qew, dvp or cogitate).

To check that you have modified your .cshrc file correctly, execute

        which f77

You should get

        /local/lib/SUNWspro/bin/f77

After you have done that, you should also add the line

        alias f77 'f77 -u -C'

to your .cshrc file.  This will cause f77 to check 

    1. check array references for out of range subscripts
    2. report undeclared variables

each time you run f77.
