For more information on the Fortran compiler, the assembler and linker, refer to the documentation listed in the Preface or to the appropriate manuals supplied with your system. The following examples show several driver options that should be available on most systems. The command-lines and output may differ on your system. By default, the executable output is placed in the file a.out . You can use the -o option to specify the output file.
Case is significant for options and their arguments.
For example, the -Mextend option specifies that the compiler accepts extended 132 column lines. The order of options and the filename is not fixed. That is, you can place options both before and after the filename argument on the driver command line. However, the placement of some options is significant, for example the -l option. If two or more options contradict each other, the last one in the command line takes precedence.
