Passing Variable back to batch script

Question

I need to pass the result of a sql script back to the calling batch script. How would I do this? This is what I have tried
Batch Script
return_code = 'sqlplus loginname/pass@database path/sqlscript.sql'
echo $return_code
sqlscript
Declare
v_locked varchar2(1);
Begin
SELECT locked into v_locked FROM program_lock
WHERE program = 'xxx';
end;
exit v_locked;

Answer 1

I already tried the option you suggested.
This is what I have in my dynamic script:
PROMPT(SELECT,PR_CTR,,"Select the Profit Center","%ENTITY_DIM%")
INFO(EQU,=)
INFO(TAB,;)
TASK(ZBPC_REVAL_SCRIPT_RUN,SUSER,%USER%)
TASK(ZBPC_REVAL_SCRIPT_RUN,SAPPSET,%APPSET%)
TASK(ZBPC_REVAL_SCRIPT_RUN,SAPP,%APP%)
TASK(ZBPC_REVAL_SCRIPT_RUN,LOGICFILENAME,COPY_ACTUALS.LGX)
TASK(ZBPC_REVAL_SCRIPT_RUN,REPLACEPARAM,PR_CTR%EQU%%PR_CTR%)
This is what I have in script logic
*SELECT(%CURRENT_CYCLE%, "[ID]", "PLAN_CYCLE", "[COMPARISON] ='CURRENT' ")
*XDIM_MEMBERSET ACCOUNT=BPC711000
*XDIM_MEMBERSET CURRENCY=LC
*XDIM_MEMBERSET DATASOURCE=ACTUALS
*XDIM_MEMBERSET EMPLOYEE=BAS(<ALL>)
*XDIM_MEMBERSET TIME=BAS(2010.TOTAL)
*XDIM_MEMBERSET PLAN_CYCLE=%CURRENT_CYCLE%
*XDIM_MEMBERSET PROFIT_CTR=$PR_CTR$
*START_BADI  FILTER_PLAN
  QUERY = ON
  WRITE = ON
*END_BADI
When I run the DM Package I get the error Memebr  :$PR_CTR$ not exist
