	invokes the no-rewind option and issue multiple segyread
	commands (making an appropriate shell script if you
	want to save all the headers).	Consider using >> if
	you want a single trace file in the end.  Similar
	considerations apply for multiple reels of tapes,
	but use the standard rewind on end of file.

 Note: For buff=1 (default) tape is accessed with 'read', for buff=0
	tape is accessed with fread. We suggest that you try buff=1
	even with EXABYTE tapes.
 Caveat: may be slow on an 8mm streaming (EXABYTE) tapedrive
 Warning: segyread or segywrite to 8mm tape is fragile. Allow sufficient
	time between successive reads and writes.
 Warning: may return the error message "efclose: fclose failed"
	intermittently when segyreading/segywriting to 8mm (EXABYTE) tape
	even if actual segyread/segywrite is successful. However, this
	error message may be returned if your tape drive has a fixed
	block size set.
 Caution: When reading or writing SEG-Y tapes, the tape
	drive should be set to be able to read variable block length
	tape files.
