RE: Logical files

[Joe Giusto <JGiusto@xxxxxxxxxxxx>]

Try RMVM from the logical file and then ADDLFM using the DTAMBRS parm to
point to the new file.

        There is no command I know of that will change a logical file to
point to a
        different physical file.  Once the logical is created, and the link
to the
        physical established, that's it.  If you have the source code for
the
        logical file, just compile it into the library where the physical
file
        lives.

        You -can- clone a logical file, assuming you have 2 identical files
(same
        record layout, format names, etc. etc.) in 2 separate libraries, 1
of which
        has a logical file pointing to it.

        1) Make sure that both the logical and the physical it references
are in
        the same library!  THIS IS VERY IMPORTANT!  If they are not in the
same
        library, use the MOVOBJ command so they are.  You can move the
logical back
        where it came from once you're done cloning it.

        2) Use the CRTDUPOBJ command and duplicate the LF to the library
where the
        2nd physical file lives.

        Done!  Move the 1st logical file back where it came from.
