set ncl logfile filespecification.ncl

    This command, coupled with the "enable ncl logging" command,
    will start the logging of an NCL session to the file specified.
    To determine the name of the log file later on, use the "show
    ncl logfile" command.

    For example, on OpenVMS:

    NCL>set ncl logfile test
    NCL>enable ncl logging
    NCL>show all
    NCL>disable ncl logging
    NCL>show ncl logfile
    Logfile name is: test
    Logfile is Disabled

    The results will be in the file TEST.NCL.  That file will
    contain the logged NCL command(s), and the output will be
    commented out.  You may then reissue the command(s) you logged
    by:

    NCL>do test.ncl
