The CTF Viewer enables you to display trace files using annotations to replace component identifiers such as “MF.RTS” and event identifiers such as “6” with more meaningful textual descriptions.
Annotation files are supplied in the %ProgramFiles(x86)%\Micro Focus\Visual COBOL\etc\mftrace\annotations (Windows) or $COBDIR/etc/mftrace/annotations (UNIX) directory. There is one annotations file for each supported component.
