Output of listings
The compiler can generate the following listings during the compilation run:
|
The compiler writes each requested listing to a separate cataloged file by default. The listings stored in cataloged files can then be printed at any time by using the PRINT-FILE command (see “Commands” manual [3]).
Instead of being written to cataloged files, the requested listings can also be written as elements in a PLAM library.
If desired, the user can have the requested listings output to the system file SYSLST by means of an appropriate control statement. The system automatically sends the temporary file created for this purpose to the printer.
The generation and output of listings can be controlled by the user via
the SDF option LISTING (see the chapter "Controlling the compiler via SDF") or
the COMOPT statements LISTFILES, LIBFILES or SYSLIST (see the chapter "Controlling the compiler with COMOPT statements").
If the POSIX subsystem is available, listings (with the exception of the object listing) can be output to the POSIX file system. This option is described in section "LISTING option".
Output of messages
All compiler messages related to the execution of the compilation run (COB90xx) are output to the terminal via the system file SYSOUT by default.
The texts of all the COB90xx messages that can be issued by the compiler are listed, together with comments, in chapter "Messages of the COBOL2000 system".
