                 'Csubc'  serves as the Subsystem interface to the Prime DBMS
                 Cobol subschema compiler (CSUBS).  It  examines  its  option
                 specifications  and  checks  them  for consistency, provides
                 Subsystem-compatible default file names for the listing  and
                 output  files  as  needed,  and then produces a Primos CSUBS
                 command and causes it to be executed.

                 The "-l" option is used to select the name of  the  file  to
                 receive  the  listing  generated by the compiler.  If a file
                 name  follows  the  option,  then  that  file  receives  the
                 listing.   If  the  "-l"  option is specified without a file
                 name following it or is not specified, a default filename is
                 constructed from the input filename by changing  its  suffix
                 to   ".l".    For   example,   if   the  input  filename  is
                 "gonzo.csub", the listing file will  be  "gonzo.l";  if  the
                 input filename is "bar", the listing file will be "bar.l".

                 The  input filename must be a disk file name (conventionally
                 ending in ".csub").

                 In summary, then, the default command line for  compiling  a
                 file named "file.csub" is

                      csubc  file.csub  -l file.l

                 which corresponds to the CSUBS command

                      csubs -i *>file.csub -l *>file.l

                 'Csubc' pays no attention to standard ports.
                 
                 There is no way to avoid getting a listing file.
