Declarations

     IMPLICIT NONE

Brief_I/O

     VARIABLE  I/O  DESCRIPTION
     --------  ---  --------------------------------------------------
     ARRFRM     I   Integer array to be moved.
     NDIM       I   Number of elements to copy, i.e. the dimension
                    of ARRFRM and ARRTO.
     ARRTO      O   Destination array.

Detailed_Input

     ARRFRM   is an array from which to copy items.

     NDIM     is the number of items to copy.

Detailed_Output

     ARRTO    is the array to which items should be copied.

Parameters

     None.

Exceptions

     Error free.

Files

     None.

Particulars

     This routine is simply shorthand for the following 3 lines of
     code.

             DO I = 1, NDIM
                ARRTO(I) = ARRFRM(I)
             END DO

Examples

     Often one needs to make a temporary copy of an array so that
     it can be manipulated without altering the original array.
     As pointed out in particulars, you could just do this within
     the code that needs the copy. However, if you have several
     arrays to copy, you can cut the number of lines of code that
     are needed by a third.

     For example:

          DO I = 1, 19
             TEMPA(I) = A(I)
          END DO

          DO I = 1, 38
             TEMPB(I) = B(I)
          END DO

     Can be rewritten as

          CALL MOVEI ( A, 19, TEMPA )
          CALL MOVEI ( B, 38, TEMPB )

Restrictions

     None.
