XL Fortran is
a command-line compiler. Invocation commands and options can be selected
according to the needs of a particular Fortran application.
Invoking the compiler
The compiler invocation commands perform all necessary
steps to compile Fortran source
files, assemble any .s and .S files, and
link the object files and libraries into an executable program.
Specifying compiler options
Compiler options perform a variety of functions, such as
setting compiler characteristics, describing the object code to be
produced, controlling the diagnostic messages emitted, and performing
some preprocessor functions.
