Portability Function or Subroutine: Returns the current system date. DATE can be used as a portability routine or as an intrinsic procedure. It is an intrinsic procedure unless you specify USE IFPORT.
Portability Subroutine: Returns the current system date.
Intrinsic Subroutine (Generic): Returns character and binary data on the real-time clock and date. Intrinsic subroutines cannot be passed as actual arguments.
Portability Functions: Compute the double-precision values of Bessel functions of the first and second kinds.
Elemental Intrinsic Function (Generic): Converts a number to double-precision real type.
Portability Function: Returns the elapsed time in seconds since the start of the current process.
Elemental Intrinsic Function (Specific): Converts the argument to double complex type. This function cannot be passed as an actual argument.
Statement: Frees the storage allocated for allocatable variables and nonprocedure pointer targets (and causes the pointers to become disassociated).
General Compiler Directives: DECLARE generates warnings for variables that have been used but have not been declared (like the IMPLICIT NONE statement). NODECLARE (the default) disables these warnings.
OpenMP* Fortran Compiler Directive: Generates a SIMD procedure.
