V301 Copy an Array

Routine ID: V301
Author(s): R.K. Böck, C. Letertre	Library: KERNLIB
Submitter:	Submitted: 01.03.1968
Language: Fortran or Assembler	Revised: 16.09.1991

These routines copy a continuous string of words into a continuous set of locations.

Structure:

SUBROUTINE subprograms
User Entry Names: UCOPY, UCOPIV, UCOPYN, UCOPY2, USWOP
External References: LOCF (N100) (Fortran version of UCOPY2 only)

Usage:

    CALL UCOPY(A,X,N)

copies N words from A into X; the beginning of A may overlap the end of X.

    CALL UCOPY2(A,X,N)

copies N words from A into X, any overlap is allowed.

    CALL UCOPYN(IA,IX,N)

transfers into IX the negative values of N integer words from IA; the beginning of IA may overlap the end of IX. (For numbers of type REAL, use VCOPYN (F121).)

    CALL UCOPIV(A,X,N)

copies N words from A into X, in reverse order, i.e.

X(1)=A(N),...,X(N)=A(1)

. No overlapping is allowed.

    CALL USWOP(A,B,N)

exchanges the first

N ≥0

words of arrays A and B. A and B must not overlap.
For

N=0

the above routines act as 'do-nothing'.
