ISAPI subroutines provide a mechanism that outputs log information to a log file. This log information is very useful because you can change the settings for it without changing an application. For information on settings, see "ISAPI Subroutine Environment Variable Settings" in Chapter 4. Note that this log information is a log of ISAPI subroutine activity only and is not useful for tracing the application itself. It should thus be used only as a guide. A log file has contents with the following structure:
process-ID thread-ID year-month-day hour: minute: second significance message
Specifically speaking, the contents are as follows:
0000000188 0000000187 1999-02-02 11:48:07 02 COB-06310:COBW3: Specified conversion name is already registered. Conversion information already registered will be enabled. 0000000188 0000000081 1999-02-02 11:48:10 01 COB-04470:COBW3: Because specified conversion information is not registered, it could not be changed.
To collect trace information of the actual application, use the TRACE function of COBOL. For details about the TRACE function, see the " NetCOBOL Debugging Guide."
