If you will be using the compiler and linker from the command line, specify the options needed on the DF command line (as described in Using the Compiler and Linker from the Command Line). You can use the functional categories of options below to locate the options needed for your application.
If you will be using the compiler and linker from the Microsoft visual development environment, select the options needed by using the various tabs in the Project menu Settings item (see Project Settings). The following graphic shows a sample Fortran tab:
The options are grouped under functional categories (the initial Category is General, as shown) to help you locate the options needed for your application. From the Fortran tab, you can select one of the following categories from the Category drop-down list (exception: those options listed in the Miscellaneous category below):
If a compiler option is not available in the dialog boxes, you can enter the option in the lower part of the Project Settings dialog box just as you would at the command line (under Project Options:).
The following tables list the Visual Fortran compiler options by category in the Fortran tab:
