I'd probably use sqlplus myself (see;
http://asktom.oracle.com/~tkyte/flat/index.html
for some tools).

PL/SQL can do it, it might look like:

create or replace function  dump_csv( p_query     in varchar2,
                                      p_separator in varchar2 
                                                    default ',',
                                      p_dir       in varchar2 ,
                                      p_filename  in varchar2 )
return number
AUTHID CURRENT_USER
is
    l_output        utl_file.file_type;
    l_theCursor     integer default dbms_sql.open_cursor;
    l_columnValue   varchar2(2000);
    l_status        integer;
    l_colCnt        number default 0;
    l_separator     varchar2(10) default '';
    l_cnt           number default 0;
begin
    l_output := utl_file.fopen( p_dir, p_filename, 'w' );
 
    dbms_sql.parse(  l_theCursor,  p_query, dbms_sql.native );
 
    for i in 1 .. 255 loop
        begin
            dbms_sql.define_column( l_theCursor, i, 
                                    l_columnValue, 2000 );
            l_colCnt := i;
        exception
            when others then
                if ( sqlcode = -1007 ) then exit;
                else
                    raise;
                end if;
        end;
    end loop;
 
    dbms_sql.define_column( l_theCursor, 1, l_columnValue, 
                            2000 );
 
    l_status := dbms_sql.execute(l_theCursor);
 
    loop
        exit when ( dbms_sql.fetch_rows(l_theCursor) <= 0 );
        l_separator := '';
        for i in 1 .. l_colCnt loop
            dbms_sql.column_value( l_theCursor, i, 
                                   l_columnValue );
            utl_file.put( l_output, l_separator ||  
                                    l_columnValue );
            l_separator := p_separator;
        end loop;
        utl_file.new_line( l_output );
        l_cnt := l_cnt+1;
    end loop;
    dbms_sql.close_cursor(l_theCursor);
 
    utl_file.fclose( l_output );
    return l_cnt;
end dump_csv;
/
 
 
You would use that for example like this:
 
create or replace procedure test_dump_csv
as
    l_rows  number;
begin
    l_rows := dump_csv( 'select * 
                           from all_users 
                           where rownum < 25', 
                        ',', '/tmp', 'test.dat' );
end;
/

Make sure to read about the INIT.ORA parameters (utl_file_dir) you need to setup !!!

Your export command is exporting IXF file, you just need to change it to DEL instead of IXF.
