cefdmp/xcefdmp

The event dump utility (cefdmp) can display, in a readable ASCII format, events from the data files.

Syntax

% cefdmp [filename] [-o object] [-t tag] [-u uniquetag] [-s start] [-e end] [-d dictionary] [-x] 
% xcefdmp [same] 

Options

o specify the source object name (CODA component name) 
t select specified tag number or name (full path in event structure) 
u select specified unique tag, independent of location in the event 
s number of first record in file to dump 
e number of last record in file to dump 
d specify dictionary for obtaining tag names and titles 
x hex dump of integers (default is decimal) 

cedit and dbedit

Use cedit and/or dbedit to modify CODA database.
