Glossary R
random access  |  
     See direct access.  |  
    
rank  |  
     The number of dimensions of an array. A scalar has a rank of zero.  |  
    
rank-one object  |  
     A data structure comprising scalar elements with the same data type and organized as a simple linear sequence. See also scalar.  |  
    
real constant  |  
     A constant that is a number written with a decimal point, exponent, or both. It can have single precision (REAL(KIND=4)), double precision (REAL(KIND=8)), or quad precision (REAL(KIND=16)).  |  
    
record  |  
     Can be either of the following: 
  |  
    
record access  |  
     The method used to store and retrieve records in a file.  |  
    
record structure declaration  |  
     A block of statements that define the fields in a record. The block begins with a STRUCTURE statement and ends with END STRUCTURE. The name of the structure must be specified in a RECORD statement.  |  
    
record type  |  
     The property that determines whether records in a file are all the same length, of varying length, or use other conventions to define where one record ends and another begins.  |  
    
recursion  |  
     Pertains to a subroutine or function that directly or indirectly references itself.  |  
    
reduction scoping clause  |  
     OpenMP* directive clauses that define the region in which a reduction is computed by tasks or Single Instruction Multiple Data (SIMD) instructions.  |  
    
reference  |  
     Can be any of the following: 
  |  
    
relational expression  |  
     An expression containing one relational operator and two operands of numeric or character type. The result is a value that is true or false. For example, A-C .GE. B+2 or DAY .EQ. 'MONDAY'.  |  
    
relational operator  |  
     The symbols used to express a relational condition or expression. The relational operators are (.EQ., .NE., .LT., .LE., .GT., and .GE.).  |  
    
relative file organization  |  
     A file organization that consists of a series of component positions, called cells, numbered consecutively from 1 to n. Intel Fortran uses these numbered, fixed-length cells to calculate the component's physical position in the file.  |  
    
relative pathname  |  
     A directory path expressed in relation to any directory other than the root directory. Contrast with absolute pathname.  |  
    
root  |  
     On Windows* systems, the top-level directory on a disk drive; it is represented by a backslash (\). For example, C:\ is the root directory for drive C. On Linux* systems, the top-level directory in the file system; it is represented by a slash (/).  |  
    
routine  |  
     A subprogram; a function or procedure. See also function, subroutine, and procedure.  |  
    
runtime  |  
     The time during which a computer executes the statements of a program.  |
