            [GREG2\]WRITE Item File_Name
            [GREG2\]WRITE  COLUMN  File_Name [OLD|NEW [Format]] /TABLE [X Nx] [Y
        Ny] [Z Nz]

        This command is used to save some GreG internal  buffers  on  an  output
        file  for  later processing. The item specifies what is to be saved, and
        the format of saving, and can be :

          POLYGON
            Save the current polygon in a formatted way on  two  columns  easily
            readable  by  command COLUMN or POLYGON later. The default extension
            is .POL

          RGDATA
            Save the current Regular Grid array on a RGDATA-like output file (to
            preserve  the result of a masking, or of a random mapping interpola-
            tion). See also HELP RGDATA FILE_FORMAT. The  default  extension  is
            .DAT

          IMAGE
            Same  as  above  but  use the more efficient and complete IMAGE data
            format of GILDAS. The default extension is .GDF

          COLUMN (no option)
            Save the current X Y Z buffers on a formatted output file  (after  a
            SORT or a STRIP for example). The default extension is .DAT

          COLUMN /TABLE
            Save  the  X  Y  Z buffers but on column Nx, Ny, Nz of the specified
            output table (Gildas Data Format). A new table is created  if  argu-
            ment  NEW is specified, otherwise the table must already exists (de-
            fault OLD). The format of NEW tables can be specified as a 4th argu-
            ment in REAL (default), DOUBLE or INTEGER. The OLD tables may be ex-
            panded if any of Nx, Ny or Nz exceed the table column number ; exact
            match  on the number of lines is required. The tables can be read by
            command COLUMN /TABLE.
