Chapter 5 Map Information Operations

The header file, stored as /u[sr]/ltp/maps/map_name/header, contains
information relevant to the current, active map.  Some of the parameters in the
header affect the processing environment, while others provide valuable data
which can be integrated into a file header for some of the export formats.
The header command allows the user to update and/or display the header file.

header

    Updates/displays the header file.
     
         header [-p] [item=arg] ...

    Display and/or modify the header file for the active map.  Multiple
    item=string pairs are allowed per execution of header.  The -p option
    prints the header file to the default primary printer.
