What the Compiler Does by Default

By default, the compiler driver generates executable file(s) of the input file(s) and performs the following actions:

For unspecified options, the compiler uses default settings or takes no action.

You may want to use the -assume keyword (Linux OS and Mac OS X) or /assume:keyword (Windows OS) option to instruct the compiler to make certain assumptions. For example, -assume buffered_io tells the compiler to accumulate records in a buffer. For more information and the complete list of supported keywords, see the assume option reference page.

Note iconNote

On operating systems that support characters in Unicode* (multi-byte) format, the compiler will process file names containing Unicode* characters.
