The CTF perspective consists of the COBOL Explorer and Properties views in the left-hand side of the IDE and the Bookmarks view in the bottom right of the IDE. The remainder of the IDE is the editor area and is used for the display of trace file contents.
You can display the CTF perspective, like any other perspective, by clicking Window > Open Perspective > Other > CTF.
We recommend that you select the CTF perspective to view trace files. By default, you are prompted to do this, if the perspective is not already current when you attempt to open a trace file. If you don't want to be prompted, you can configure the default behavior by going to Window > Preferences > Micro Focus > Consolidated Trace Facility.
