Hi Brian--

    You have some other error, if file2 is the newly-created file. There
is no OS/2 restriction against copying an open file to another file.
There _is_ a restriction against copying a file _to_ an open file.

    In any case, in answer to your query, use the stream function:

      Call STREAM file2, 'c', 'close'  /* file2 is the "from" file */

    Next time, post your REXX queries in the OS2REXX echo.  You have a
possibility of finding more REXX gurus there :-).  In any case, more
REXX users are likely to learn something from your query and the
replies.
