 Collected Fortran Wisdom
 ************************
 
    Most users of `g77' can be divided into two camps:
 
    * Those writing new Fortran code to be compiled by `g77'.
 
    * Those using `g77' to compile existing, "legacy" code.
 
    Users writing new code generally understand most of the necessary
 aspects of Fortran to write "mainstream" code, but often need help
 deciding how to handle problems, such as the construction of libraries
 containing `BLOCK DATA'.
 
    Users dealing with "legacy" code sometimes don't have much
 experience with Fortran, but believe that the code they're compiling
 already works when compiled by other compilers (and might not
 understand why, as is sometimes the case, it doesn't work when compiled
 by `g77').
 
    The following information is designed to help users do a better job
 coping with existing, "legacy" Fortran code, and with writing new code
 as well.

* Advantages Over f2c        If `f2c' is so great, why `g77'?
* Block Data and Libraries   How `g77' solves a common problem.
* Loops                      Fortran `DO' loops surprise many people.
* Working Programs           Getting programs to work should be done first.
* Overly Convenient Options  Temptations to avoid, habits to not form.
* Faster Programs            Everybody wants these, but at what cost?
