    Read an ASCII file of lines (frequency in GHz and  name)  into  the  SIC
    structure  named  CLASS%LINE. When the filename is missing, CATALOG uses
    by default the ASTRO line catalog. Each row of the  line  file  contains
    the description of a line as follows:

       115.271204      12CO-1-0

    Comment  lines  start with the exclamation mark (!). By default the line
    catalog is sorted by increasing frequency. This can be changed by  using
    the option /SORT.

    The SIC structure containing the catalog has 3 members:
       CLASS%LINE%N        [     integer] number of lines read
       CLASS%LINE%FRES[N]  [      double] line frequency in MHz
       CLASS%LINE%NAME[N]  [character*12] line name
