SUBROUTINE ARR_FLIP1R( N, IN, OUT, STATUS )
*+
* Name:
* ARR_FLIP1R
* Purpose:
* Flip one dimensional array of REAL values
* Language:
* Starlink Fortran
* Invocation:
* CALL ARR_FLIP1R( N, IN, OUT, STATUS )
* Description:
* Reverses the order of the values in the array IN, writing them to
* the array OUT.
* Arguments:
* N = INTEGER (given)
* The number of values in the input array
* IN = REAL[] (given)
* The values to flip
* OUT = REAL[] (returned)
* The flipped array
* STATUS = INTEGER (given)
* The global status.
* Examples:
* {routine_example_text}
* {routine_example_description}
* Pitfalls:
* Due to the simple way this routine is implemented IN and OUT must
* be different arrays.
