 BHPMAKEEVENT -  Build NULL Event Trace                               

 bhpmakeevent [optional parameters]                                   

 bhpmakeevent makes BHPIO event data consisting of all NULL events,   

 or adds NULL events to an existing BHPIO event dataset.              

 Required parameters: none                                            

 Optional parameters:                                                  

 filename=stack     Name of existing BHPIO cross-section cube dataset 

 pathlist=stack.dat File containing filename partitions               

                    The output dataset is created with bhpwritecube,  

                    and is automatically named 'filename_events'.     

                    A pathlist file is created in the same directory  

                    as pathlist.                                      

 endian=2           Use native endianness for output data. Specify    

                    endian=0 to write LITTLE, or endian=1 to write BIG,

                    regardless of the platform on which bhpmakeevent is

                    running.                                          

 type=new           Replace samples of input data with all NULLs.     

                    Use type=append to add NULLs to existing input data.

                    If type=new, input data must be in cross-section  

                    order, but may be of any type: seismic, model, or 

                    event. If type=append, input data must be event data

                    in cross-section order.                           

 ename=null         Partial name to use for new events. Actual names will

                    be 'ename'1, 'ename'2,...                         

 num=20             Number of NULL events to create or append.        

 null=-999.25       Value to use for null                             

 verbose=0          Use verbose=1 for long printout
