15 Compiler Directives

Compaq Fortran provides the following compiler directives:

• General directives

  Perform general-purpose tasks during compilation (see Section 15.1).

• Parallel directives (TU*X only)

  Specify parallel regions, and characteristics of data and threads for shared access of data in memory (see Section 15.2).

• High Performance Fortran directives (TU*X only)

  Specify data layout and other characteristics when compiling for parallel execution (see Section 15.3).

Compiler directives are preceded by a special prefix that identifies them to the compiler.
