The TRACE utility provides the Common Trace Facility command interface
 that allows you to collect and display information that passes between
 protocol layers in a network.  CTF commands allow you to start tracing
 data, stop tracing, and display an analysis of the traced information.

 The following process privileges are required to use CTF:

 ALTPRI, BYPASS, CMKRNL, NETMBX, PRMGBL, PRMMBX, PSWAPM, SYSGBL, SYSLCK,
 SYSNAM, TMPMBX, WORLD

 To run the TRACE utility, enter the command:

         TRACE

 The prompt CTF> will appear, indicating that you may enter CTF commands.

 Alternatively, you can enter a CTF command directly from DCL:
