Portability Subroutine: Returns a pseudorandom number greater than or equal to zero and less than one from the uniform distribution.
RANDOM_NUMBER
Intrinsic Subroutine: Returns one pseudorandom number or an array of such numbers.
RANDOM_SEED
Intrinsic Subroutine (Generic): Changes or queries the seed (starting point) for the pseudorandom number generator used by intrinsic subroutine RANDOM_NUMBER. Intrinsic subroutines cannot be passed as actual arguments.
RANDU
Intrinsic Subroutine (Generic): Computes a pseudorandom number as a single-precision value. Intrinsic subroutines cannot be passed as actual arguments.
RANF
Portability Function: Generates a random number between 0.0 and RAND_MAX.
RANGE
Inquiry Intrinsic Function (Generic): Returns the decimal exponent range in the model representing numbers with the same kind parameter as the argument.
RANGET
Portability Subroutine: Returns the current seed.
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 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*32)
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*32)
QuickWin Function: Registers the application-supplied callback routine to be called when a specified mouse event occurs in a specified window.
REMAPALLPALETTERGB, REMAPPALETTERGB (W*32)
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.
RGBTOINTEGER (W*32)
QuickWin Function: Converts three integers specifying red, green, and blue color intensities into a four-byte RGB integer for use with RGB functions and subroutines.
RINDEX
Portability Function: Locates the index of the last occurrence of a substring within a string.
RNUM
