Calling C routines from HP Fortran
Case sensitivity
Chapter 8 185
If you use the $HP$ ALIAS directive in many of the Fortran source files in your program, you
may find it convenient to define all of the directives in one file and include that file in all of the
Fortran source files with the +pre_include=file option. This option takes one argument, file,
which is the name of the file you want to include. All text in file is prepended to each of the
source files specified on the command line, before being passed to the compiler.
See “File handling” on page 193 for another example of a program that uses the $HP$ ALIAS
directive. The HP Fortran Programmer's Reference fully describes the %VAL and %REF built-in
functions, the +uppercase and +pre_include options. Th e $HP$ ALIAS directive is discussed
in “$HP$ ALIAS” on page 203.
