To enable CTF tracing

1. Set the MFTRACE_CONFIG environment variable to point to the configuration file, before you invoke the application. For example:

   set MFTRACE_CONFIG=c:\ctf\ctf.cfg

2. Specify the format of CTF trace files you require by adding the appropriate lines in the configuration file ctf.cfg, such as:

   mftrace.dest = binfile 

   mftrace.emitter.binfile#location  = c:\logs

   mftrace.level.mf.rts              = info
   mftrace.comp.mf.rts#pgm           = true
   mftrace.comp.mf.rts#pgmload       = true
   mftrace.comp.mf.rts#syspgm        = true
   

3. Set the MFTRACE_LOGS environment variable to specify the location in which to create the CTF log files. If MFTRACE_LOGS is not set, the current folder is used. Your COBOL development system's command prompt sets MFTRACE_LOGS to the base\mftrace\logs directory.
4. Run the application from the environment you set up.
