Library /sys$common/syshlp/ctf$help.hlb ANALYZE, /TRACE_LEVEL  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  /TRACE_LEVEL=(protocol-identifier,...)

 	Normally, CTF will display the analysis for a single protocol,
 	even if the trace file contains trace records from more than
 	one protocol. By default, CTF will analyze only those trace
 	records with the same protocol as the first trace record in
 	the trace file.

 	However, if you use this qualifier, all the specified
 	protocols will be analyzed.

 	You cannot use this qualifier with either /FILTER or /SELECT.
