Compiler directives tell the compiler to perform certain tasks when it compiles a source program unit. They are preceded by special tags that identify them to the compiler. These compiler directives are grouped as follows:
Perform several general-purpose functions; they are preceded by the cDEC$ tag (see Section 11.1).
Support directed decomposition for parallel processing; they are preceded by the cPAR$ tag (see Section 11.1).
For details on a statement that overrides or confirms compiler options within a program unit, see the OPTIONS statement in Section 1.6.3.
