  BHPWRITEVOL - Convert SU data to GeoProbe Volume            

  32-bit floating-point trace data are converted to 8-bit integer,

  which can be loaded into the Magic Earth GeoProbe product.  

  bhpwritevol < stdin > stdout  [optional parameters]         

  stdout MUST BE a disk file, not a pipe                       

  NOTE: Input data must be in 'survey Y,survey X' order.      

        If inlines vary along the survey Y axis, the data must

        be sorted by inline,crossline, else if crosslines vary

        along the survey Y axis, data must be sorted by       

        crossline,inline.                                     

  Required Parameters: None                                    

  Optional Parameters:                                        

  ilhdr=ep          Trace header to use for inline numbers    

  xlhdr=cdp         Trace header to use for xline numbers     

  survey=xline      Survey orientation; xline means crosslines

                    vary along survey X axis and inlines vary 

                    along the Y axis; iline means the inverse 

  clip=7.5          Trace data values larger than clip*RMS    

                    are clipped before conversion to 8-bit data

  endian=1          Endianness of output data. Default is     

                    BIG. Use endian=0 to write LITTLE.        

  verbose=0         =1 for debug printout
