Compaq Fortran provides several general-purpose compiler directives to perform tasks during compilation. You do not need to specify a compiler option to enable general directives.
This section describes syntax rules and the following directives:
Specifies an alternate external name to be used when referring to external subprograms.
Specifies properties for data objects and procedures.
Generates or disables warnings for variables that have been used but not declared.
Specifies a symbolic variable whose existence (or value) can be tested during conditional compilation.
Sets the line length for fixed-form source code.
Specifies free-format or fixed-format source code.
Specifies an identifier for an object module.
Specifies a conditional compilation construct.
Specifies the default integer kind.
Assists the compiler's dependence analysis.
Specifies a character string to be sent to the standard output device during the first compiler pass.
Specifies a library search path in an object file.
Affects data alignment and warnings about data alignment.
Specifies the memory starting addresses of derived-type items.
Modifies certain characteristics of a common block.
Specifies the default real kind.
Disables or enables language features not found in the language standard specified on the command line (Fortran 95 or Fortran 90).
Specifies a title or subtitle for a listing header.
Tells the compiler's optimizer how many times to unroll a DO loop.
