VMS Help RTL Routines, SMG$, SMG$SET_CURSOR_REL  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Move Cursor Relative to Current Position routine moves the
    virtual cursor the specified number of rows and columns from the
    current virtual cursor position in a virtual display.

    Format

      SMG$SET_CURSOR_REL  display-id [,delta-row] [,delta-column]

1 - Returns

    OpenVMS usage:cond_value
    type:         longword (unsigned)
    access:       write only
    mechanism:    by value

2 - Arguments

 display-id

    OpenVMS usage:identifier
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference

    Specifies the virtual display in which to move the virtual
    cursor. The display-id argument is the address of an unsigned
    longword that contains the display identifier.

    The display identifier is returned by SMG$CREATE_VIRTUAL_DISPLAY.

 delta-row

    OpenVMS usage:longword_signed
    type:         longword (signed)
    access:       read only
    mechanism:    by reference

    Specifies the number of rows to move the virtual cursor. The
    delta-row argument is the address of a signed longword that
    contains the number of rows to move. If omitted, the virtual
    cursor remains at the current row position. If delta-row is
    positive, the virtual cursor moves downward the specified number
    of rows. If delta-row is negative, the virtual cursor moves
    upward the specified number of rows.

 delta-column

    OpenVMS usage:longword_signed
    type:         longword (signed)
    access:       read only
    mechanism:    by reference

    Specifies the number of columns to move the cursor. The delta-
    column argument is the address of a signed longword that contains
    the number of columns to move. If omitted, the virtual cursor
    remains at the current column position. If delta-column is
    positive, the virtual cursor moves the specified number of
    columns to the right. If delta-column is negative, the virtual
    cursor moves the specified number of columns to the left.
