SEGYHDRS - make SEG-Y ascii and binary headers for segywrite

segyhdrs [ < sudata ] [optional parameters] [ > copy of sudata ]

Required parameters:
ns= if no input trace header
dt= if no input trace header
Optional parameters:
ns=tr.ns from header number of samples on input traces
dt=tr.dt from header sample rate (microseconds) from traces
bfile=binary name of file containing binary block
hfile=header name of file containing ascii block
Some binary header fields are set:
jobid=1 job id field
lino=1 line number (only one line per reel)
reno=1 reel number
format=1 data format

All other fields are set to 0, by default.
To set any binary header field, use sukeyword to find out
the appropriate keyword, then use the getpar form:
keyword=value to set keyword to value

The header file is created as ascii and is translated to ebcdic
by segywrite before being written to tape. Its contents are
formal but can be edited after creation as long as the forty
line format is maintained.

Caveat: This program has not been tested under XDR for machines
not having a 2 byte unsigned short integral data type.
