.SH NAME
sdssdtoa \- convert SDS sampled data file to machine-independent format for input to atosps
.SH SYNOPSIS
.B sdssdtoa
[
.I infile
] [
.I outfile
]
.SH DESCRIPTION
.PP
.I Sdssdto
converts an SDS sampled data file to a machine-independent, 
ASCII format suitable for input to \fIatosps\fR. 
The output can be converted to an SPS sampled data file
by the 
.I atosps
program.
.PP
If the first argument is missing or is "\-",
.I sdssdtoa
will read from the standard input.
If the second argument is missing or is "\-",
it will write to the standard output.
Integer and character values are represented exactly in the output; float
values retain seven significant digits; double precision values retain 15
significant digits.
.PP
The program can only operate on SDS sampled data files that contain
SDS headers of type FT_SAMPLED_DATA.    
.PP
An SDS sampled data file can be converted to SPS by the pipeline:
.br
sdssdtoa FILE_sds.sd | atosps  FILE_sps.sd
.PP
A shell script is available (\fIsdconvert\fR) that does this
conversion.
.SH SPS PARAMETERS
.PP
This program does not access the parameter file.
.SH DIAGNOSTICS
.PP
.I Sdssdtoa
informs the user and quits if the input file does not exist or is not an SDS
file sampled data file.
.SH BUGS
.PP
This is a modified version of the SDS program \fIsdstoa\fR that only
operates on SDS sampled data file.     Header items are from the SDS
file are mapped onto the correct SPS header items.    Only embedded
headers of type FT_SAMPLED_DATA are handled by the program.
