Intrinsic procedures

Four categories

• Elemental procedures
  
  A set of functions and one sub-routine, specified for scalar arguments, but appli-cable for conforming array arguments,

• Inquiry functions
  
  Return properties of principal arguments that do not depend on their values

• Transformational functions
  
  usually have array arguments and an array result whose elements depend on many of the elements of the arguments

• Nonelemental subroutines

New intrinsic procedures
