56 Getting Started
The Less button compacts this dialog to display only the four buttons on top to minimize any obscuring of
the Monitor window. This is useful when you have configured the search parameters and want to repeat
the same search query many times. While compacted, this button changes to
More enabling the user to
force the dialog back to its expanded format. The Tag All button launches a search throughout the trace
buffer for the specified search criteria and will tag all lines which match. After this type of search is
completed, you can use the
Go to Tagged Row tool bar button on the Monitor window to easily locate
and step through all of these lines. The Find Next button simply moves the Monitor trace list to the next
found line matching the search criteria. This action can be repeated to locate all matching lines, but
without tagging them. If the end of the buffer if reached, the search will wrap and continue at the start of
the trace buffer.
The various fields are intuitive for defining search criteria and allow searching over a wide range of
conditions from very specific to entire classes of trace lines. The mask feature allows enabling/disabling
individual bits when looking for a single-byte data pattern. The
Byte Position indicates which data byte in
a message is to be considered. The Width field may not be modified and is locked at one byte for search
data values.
When the user clicks on the Load From Selected Monitor Trace Line button, the characteristics of the
currently selected line in the trace buffer are used to populate the Find dialog. The user can then tweak
any needed changes to the search criteria fields. This facilitates searching for the same or similar lines
throughout the trace buffer with a minimal amount of manual data entry. Each field’s pull-down will supply
common selections, previously entered values, or defined symbols, as appropriate. Otherwise, type in the
desired values.
