CTTAFR – Format and Initialize Trace File

The CTTAFR utility formats and initializes the Trace file. The physical block number of the Trace file is automatically specified in the PARM parameter of the JCL EXEC statement. This value is the same as the IOA variable TRCBLKS, which was set in the ICE environment.

Note: For more information about calculating the trace file size, see the Control-M/Tape installation chapter of the INCONTROL for z/OS Installation Guide.
