- RANSET
Portability Subroutine: Sets the seed for the random number generator.
- READ Statement
Statement: Transfers input data from external sequential, direct-access, or internal records.
- REAL Statement
Statement: Specifies the REAL data type.
- REAL Directive
General Compiler Directive: Specifies the default real kind.
- REAL Function
Elemental Intrinsic Function (Generic): Converts a value to real type.
- RECORD
Statement: Declares a record structure as an entity with a name.
- RECTANGLE, RECTANGLE_W (W*S)
Graphics Functions: Draw a rectangle using the current graphics color, logical write mode, and line style.
- RECURSIVE
Keyword: Specifies that a subroutine or function can call itself directly or indirectly. Recursion is permitted if the keyword is specified in a FUNCTION or SUBROUTINE statement, or if RECURSIVE is specified as a compiler option or in an OPTIONS statement.
- REDUCTION
Parallel Directive Clause: Performs a reduction operation on the specified variables.
- %REF
Built-in Function: Changes the form of an actual argument. Passes the argument by reference. In Intel® Fortran, passing by reference is the default.
- REGISTERMOUSEEVENT (W*S)
QuickWin Function: Registers the application-supplied callback routine to be called when a specified mouse event occurs in a specified window.
- REMAPALLPALETTERGB, REMAPPALETTERGB (W*S)
Graphics Functions: REMAPALLPALETTERGB remaps a set of Red-Green-Blue (RGB) color values to indexes recognized by the video hardware. REMAPPALETTERGB remaps one color index to an RGB color value.
