*  
*    Lines which first character is an asterisk (*) are
*    supposed to be comments and can occur anywhere
*    in the input stream.
*
*    Lines which first character is the char. (@)
*    will be interpreted as commands. They must match a
*    simple pattern :
*
*      @ variable_name := string
*    
*    In the following input stream @variable_name will 
*    be substituted by string. variable_name may be up
*    to 8 chars long. Continuation lines are not allowed.
*
*    Lines which first character is a percent sign (%)
*    identify parameters that will be fitted on request.
*
*    Every valid input line (begins not with *) looks like
*          <comment> :: <data> :: <comment>
*    or like
*          <comment> :: <data>
*    and <data> is read by CONUSS with free format.
