% bhedtopar < binary outpar=binary.parwhich for the case of the header file created for the test SU data appears as follows
jobid=1 lino=1 reno=1 ntrpr=0 nart=0 hdt=4000 ...The values that are assigned to the various header files may be edited, and be reloaded into the header file via setbhed
% setbhed bfile=binary par=binary.parIndividual header field values may also be set. For example
% setbhed bfile=binary par=binary.par lino=3which uses the contents of binary.par but with the field lino set to 3.
Finally, the tape may be written via a command sequence like this
% segywrite tape=/dev/rmtx verbose=1 < data.sutaking care to note that the files ``header'' and ``binary'' are in the current working directory. You may use different names for these files, if you wish. Segywrite has a ``bfile='' and an ``hfile='' option to permit you to input the files by the different names you choose.
