Here is a script that can give you the ASCII dump. As you can see, I did not write it. Jared Still wrote it. Its beautiful !!!

• dump.sql - jared still
• jkstill_at_bcbso.com
• jkstill_at_teleport.com

• dump a table to a comma delimited ascii file
• only drawback is line length is likely to be padded with
• quite a few spaces if the 'set trimspool on' option is
• not in your version of SQLPLUS
  --
  
• also builds a control file and a parameter file for SQL*LOADER
