OpenTP1 for Windows enables you to output to a file and to the console the contents of standard output and standard error by the system server and user server (this includes KFCA-xxxxx messages and all information specified for standard output by the user).

For details about the functions for checking standard output and standard error, see 2.2 Functions for checking standard output and standard error.

The following information is output to the Windows Event Viewer:

• OpenTP1 messages (other than messages output by the installation and setup programs and operation commands)
• Messages whose output destination is indicated in the manuals OpenTP1 Version 7 Messages as being standard output or standard error.

To view OpenTP1's event logs:

1. Display the Windows Event Viewer.
2. Choose Applications.
   The application logs are displayed. An event for which OpenTP1 is displayed under Source is a message issued by OpenTP1.
   

The messages specified in the dc_logprint function or CBLDCLOG('PRINT ') are also displayed in the Windows Event Viewer. Note the following about using the dc_logprint function or CBLDCLOG('PRINT '):

• CBLDCLOG('PRINT ') ignores specification of message colors.
• If an invalid argument value is set, an error message is output to the event log in the following format:
  

  (xxx...xx) cannot be output due to an invalid message

  Legend:

  xxx...xx: Message ID

  
  
• In the message format KFCAn1n2n3n4n5-x, only -I, -R, -W, or -E can be specified for -x. If any other value is specified, the specified argument is treated as being invalid and the error message shown above is issued. Also, -x corresponds to the Type in the Windows Event Viewer. The following shows the type of information that is displayed for each -x value:
  
  • -I or -R: Informational
  • -W: Warning
  • -E: Error
