ANALYZE
/PROTOCOL=(protocol-identifier,...)
/NOPROTOCOL
Specifies the type of analysis performed on each trace record. The protocol data in
each trace record is analyzed for each of the protocols listed in the /PROTOCOL
qualifier, in the order in which they are specified. If you do not specify this
qualifier, only the protocol data supplied at the protocol level of the originating
tracepoint is analyzed; protocol data from higher levels is displayed, unanalyzed,
as user data. If you specify /NOPROTOCOL, no analysis is performed on the
protocol data in the trace record; it is all presented as user data.
/REVERSE
/NOREVERSE
Specifies that received data will be displayed in reverse video, and titles will be
displayed in bold. The default is /REVERSE.
/SAVE_BUFFER_SIZE=n
Specifies how many screens of saved lines of data will be kept. These screens can
be examined by using the NEXT and BACK commands. The default is 30. The
minimum is one screen. The maximum is 1000 screens.
/SCROLL
/NOSCROLL
Specifies whether data is displayed continuously or a page at a time. If you
specify /NOSCROLL, you have to issue the NEXT or BACK command to display
the next screen or previous screen. The default is /SCROLL, which causes data to
be displayed continuously.
/SELECT=(protocol-identifier,...)
Specifies which protocol analyses are to be displayed. This qualifier is only useful
if you have used the /PROTOCOL qualifier to request multiple protocol analysis
of a trace record. The default is to display all the protocol analyses requested by
the /PROTOCOL qualifier.
/SINCE=time
Specifies that only trace records collected since the specified time are to be
displayed. Specify the time in standard VMS format.
/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.
/TRUNCATE
/NOTRUNCATE
Specifies whether data that will not fit on one line is truncated or continued on
the next line. The default is /TRUNCATE for live tracing and /NOTRUNCATE
for analysis of a file.
/WIDTH=n
Specifies the width of the output page, in columns. If the data is written to a file,
the default is 132. If the data is displayed on your terminal, the default is the
width of your screen.
