dbexport unloads data in the pipe delimited format.
you can do dbschema -d "dbname" -t "tabname" -ss > "tabname.sql"
and the run
dbaccess "dbname" <<!!
unload to "tabname.unl"
select * from "tabname"
!!
that way you will have the schema and the unload file.
if you need to do this for multipule tables you can script this.
Cheers
