They are; read below.

6.13  Q: I want to read all the error messages that gcc throws on me, but
         they are so many that I can't keep up.  How can I redirect them
         to a file?
      Q: When I add ``-v'' to the gcc command line, how can I put all the
         voluminous output into a file, so I don't miss anything when
         reporting a problem?
      Q: I have this nifty graphics program which bombs from time to time,
         but the registers and traceback info is hidden by the graphics
         display.  How can I see it?
      A: There are several alternatives:

           1) You can put ``2r1'' into your GO32 environment variable,
              which will redirect stderr to stdout, and redirect stdout to
              a file by appending ``> file''to your command line.  See
              question 5.1 above.

           2) You can use a shell smarter then COMMAND.COM, such as 4DOS,
              which knows how to redirect standard error stream to a file.
              4DOS is shareware and can be found, e.g., on SimTel mirrors.

           3) You can add ``core file'' to your GO32 environment variable,
              to have your traceback written to the named file.  This only
              works for the exception traceback redirection (useful when
              running graphics applications).

           4) You can run your program under any one of the programs which
              save the output of programs they spawn in a file.  I suggest
              using a program called SCRIPT, which is similar to its Unix
              namesake.  It has an advantage of saving everything which
              goes to screen AND showing it on the screen at the same
              time.  SCRIPT can be found on SimTel mirrors as SCRIPT11.ZIP
              (e.g., oak.oakland.edu:/SimTel/msdos/screen/script11.zip).

3.10  Q: I've installed the 1.12m4 maintenance release, but go32 still
         displays its version as 1.12maint3.  Huh?
      A: Usually, go32 revision gets updated for each new maintenance
         release, but sometimes it won't.  When in doubt, look in the
         djXXXmN.zip to see if there is a new go32.exe there, or ask on
         the newsgroup or the mailing list (see question 20.2).
