• MASTER TASKLOOP SIMD
  OpenMP* Fortran Compiler Directive: (Deprecated; replaced by MASKED TASKLOOP SIMD) Creates a MASTER construct containing a TASKLOOP SIMD construct, with no Fortran statements in the MASTER construct that are not also in the TASKLOOP SIMD construct. This feature is only available for ifx.

• MINEXPONENT
  Inquiry Intrinsic Function (Generic): Returns the minimum exponent in the model representing the same type and kind parameters as the argument.
• MINLOC
  Transformational Intrinsic Function (Generic): Returns the location of the minimum value of all elements in an array, a set of elements in an array, or elements in a specified dimension of an array.
• MINVAL
  Transformational Intrinsic Function (Generic): Returns the minimum value of all elements in an array, a set of elements in an array, or elements in a specified dimension of an array.
• MM_PREFETCH
  Intrinsic Subroutine (Generic): Prefetches data from the specified address on one memory cache line. Intrinsic subroutines cannot be passed as actual arguments.
• MOD
  Elemental Intrinsic Function (Generic): Returns the remainder when the first argument is divided by the second argument.
• MODULE
  Statement: Marks the beginning of a module program unit, which contains specifications and definitions that can be used by one or more program units.
• MODULE FUNCTION
  Statement: Indicates a separate module procedure.
• MODULE PROCEDURE
  Statement: Identifies module procedures in an interface block that specifies a generic name.
