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 (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. . No overlapping is allowed.

    CALL USWOP(A,B,N)

exchanges the first words of arrays A and B. A and B must not overlap.
For the above routines act as 'do-nothing'.
