System Debug Reference Manual

LOG 

Controls the recording of user input to the logfile.

Syntax 

      LOG

      LOG [filename]

      LOG [ON   ]
      LOG [OFF  ]
      LOG [CLOSE]

All Debug user input can be recorded to the log file.  The log file can
be used as a playback file.

LOG, entered alone, displays the state of the log file, including the
file name, if open, and the current status (ON/OFF).

LOG filename opens the specified file and activates (turns on) the log
file.  If another log file is already opened, it is first closed (saved)
before the new file is opened.  This command does an implicit LOG ON

LOG ON and LOG OFF can be used to activate/deactivate-activate the
currently opened log file.  The file remains open (pending), but Debug
input is not recorded if the log file is OFF.

LOG CLOSE closes (saves) the current opened log file.  Note that this
command is written to the log file.  Executing this command without a log
file has no effect.

Parameters 

filename         The file name for the logfile that is to be opened.  If
                 the file already exists, it is automatically purged
                 (without warning), and reopened new.  This command
                 performs an implicit LOG ON.

                 If omitted, the status of the current log file is
                 displayed.

Examples 

     %cmdebug > log logfile 

Open a new logfile named logfile and start logging to it.

     %cmdebug > log close 

Close (and save) the current logfile.  Auto-logging is now off.

Limitations, Restrictions 

Unless a file equation is used, the list file is opened as the following:

  CCTL, FIXED, ASCII, 10000 Records, 80 byte record width.


CAUTION The output format of all System Debug commands is subject to change without notice. Programs that are developed to postprocess System Debug output should not depend on the exact format (spacing, alignment, number of lines, uppercase or lowercase, or spelling) of any System Debug command output.
