Syntax:     NAME/COLUMN table column [new-column] [unit] [format]
\ys\pa
            table      = the table name
\ap\pa
            column     = the column reference

\ap\pa
            format     = format associated to the column according to the
                         FORTRAN-77 rules with some extensions. The format 
                         is used by default when the table is displayed 
                         (commands READ/TABLE and PRINT/TABLE). 
                         Possible formats are : \\
                         for characters: Aww   \\
                         for integers: Iww    iww      \\
                                       Xww    Oww      for hexa / octal\\
                                       Tww.dd tww.dd   for Date+Time\\
                                                         (seconds since 1970)\\

                         for floating: Fww.dd fww.dd   \\
                                       Eww.dd eww.dd   \\
                                       Gww.dd  \\
                                       Rww.dd rww.dd   for Right Ascensions\\
                                       Sww.dd sww.dd   for Sexagesimal (decl.)\\
                                       Tww.dd tww.dd   for Date+Time (JD)\\
                                       Zww.dd zww.dd   zero-filled\\

Note:      
            It is not possible to CHANGE the TYPE of a column.
            However the command COPY/TT will allow you to transform a column
            of a certain type into a column of an another type.

Examples:
\ex
            NAME/COLUMN mytable \#2 :RADVEL "km.s-1" E12.3
            This command will give to the column 2 of the table mytable the 
            label RADVEL
\xe\ex
            NAME/COLUMN mytable :RADVEL :VELOCITY
            This command will give the label VELOCITY to the column of the 
            table mytable  which has the label RADVEL
\xe\ex
            NAME/COLUMN mytable \#2 "km.s-1" E12.3
            This command will give to the column 2 of the table mytable the 
            units "KM.SEC-1". The format E12.3 will be used to display the
            values of that column
