Create script from another script using PROMPT

Question

Oracle 11
Instead of having to link to another database I want to create 2 scripts that are executed from a shell script and run them separately. Script1 run in Database1 would create Script 2 by using PROMPT to create the second script while grabbing a date from database1 to pass into database2. I almost have it but the problem is ... Script2 uses COPY FROM and I have to put a "-" at the end of each line which the PROMPT takes as a literal instead of as part of the output.
SCRIPT1:
set pagesize 0
set trimspool on
set linesize 2000
set echo off
set verify off
set feedback off
set sqlblanklines on
spool /home/michelle/sql_scripts/sl_dtc_copy2.sql
PROMPT whenever sqlerror exit sql.sqlcode rollback
PROMPT SET ARRAYSIZE 5000
PROMPT SET COPYCOMMIT 20
PROMPT set linesize 4000
PROMPT
PROMPT COPY FROM {username}/{pswd}@{DB2}  TO {username}/{pswd}@{DB2}
PROMPT CREATE SL_DTC_TMP USING SELECT DISTINCT
PROMPT col1, col2, col3
PROMPT FROM dual
PROMPT WHERE veh_data_elements_cd = 'ODO_READ'
PROMPT and       dh.data_collected_timstm >= 
select trunc(sysdate)-7 from dual;
PROMPT and       substr(vdh.vin,10,1) in ('A','B','C','D')
PROMPT /
PROMPT spool off
PROMPT exit
spool off
exitSCRIPT2 NOW:
whenever sqlerror exit sql.sqlcode rollback
SET ARRAYSIZE 5000
SET COPYCOMMIT 20
set linesize 4000
COPY FROM {username}/{pswd}@{DB2}  TO {username}/{pswd}@{DB2}
CREATE SL_DTC_TMP USING SELECT DISTINCT
col1, col2, col3
FROM dual
WHERE veh_data_elements_cd = 'ODO_READ'
and       dh.data_collected_timstm >=
12-AUG-11
and       substr(vdh.vin,10,1) in ('A','B','C','D')
spool off
exitSCRIPT2 HOW IT NEEDS TO BE:
--- A [SPACE] AND A [-] at the end of each line
--- THE DATE NEEDS TO HAVE SINGLE QUOTES AND PREFERABLY AT THE END OF THE PREVIOUS LINE
whenever sqlerror exit sql.sqlcode rollback
SET ARRAYSIZE 5000
SET COPYCOMMIT 20
set linesize 4000
COPY FROM {username}/{pswd}@{DB2}  TO {username}/{pswd}@{DB2} -
CREATE SL_DTC_TMP USING SELECT DISTINCT -
col1, col2, col3 -
FROM dual -
WHERE veh_data_elements_cd = 'ODO_READ' -
and       dh.data_collected_timstm >= '12-AUG-11' -
and       substr(vdh.vin,10,1) in ('A','B','C','D')
spool off

Try
select 'whenever sqlerror exit sql.sqlcode rollback'                    ||chr(10)||
       'SET ARRAYSIZE 5000'                                             ||chr(10)||
       'SET COPYCOMMIT 20'                                              ||chr(10)||
       'set linesize 4000'                                              ||chr(10)||
       ' '                                                              ||chr(10)||
       'COPY FROM {username}/{pswd}@{DB2}  TO {username}/{pswd}@{DB2} -'||chr(10)||
       'CREATE SL_DTC_TMP USING SELECT DISTINCT -'                      ||chr(10)||
       'col1, col2, col3 -'                                             ||chr(10)||
       'FROM dual -'                                                    ||chr(10)||
       'WHERE veh_data_elements_cd = ''ODO_READ'' -'                    ||chr(10)||
       'and       dh.data_collected_timstm >= ''12-AUG-11'' -'          ||chr(10)||
       'and       substr(vdh.vin,10,1) in (''A'',''B'',''C'',''D'')'
       as Script
from dual
