WHENEVER SQLERROR EXIT SQL.SQLCODE||SQLERRM & Relate ORA-ERRNO & SQLCODE

Question

Hi,
Is there any way to pass both the SQL.SQLCODE & SQLERRM to the os back ??
When I tried WHENEVER SQLERROR EXIT SQL.SQLCODE
The actual oracle error code (ORA-00942) and the error code (174 ) returned by SQL.SQLCODE are different . So how can I get the info. that is related to SQL.SQLCODE
eg :
For this test program
rm -f /home/etladm/test/test.log
sqlplus -S <<EOF >> /home/etladm/test/test.log
ranjeeshk/ics
set verify on time on timing on term on echo on feedback on serveroutput on
WHENEVER SQLERROR EXIT SQL.SQLCODE
-- WHENEVER SQLERROR EXIT SQLERRM
select sysdate sdate from dua;
exit 1
EOF
echo "Number of rows are: $?" >> /home/etladm/test/test.log
echo " -------- Log file -------- \n"
cat /home/etladm/test/test.log
The output was
etladm@stdwdev2:/home/etladm/test>. ./test.ksh
-------- Log file --------
select sysdate sdate from dua
ERROR at line 1:
ORA-00942: table or view does not exist
Number of rows are: 174
etladm@stdwdev2:/home/etladm/test>
So how can I link ORA-00942 and SQLCODE 174 ?
with thanks in advance

From the Oracle documentation:
<quote>
The range of operating system return codes is also restricted on some operating systems. This limits the portability of EXIT n and EXIT variable between platforms. For example, on UNIX there is only one byte of storage for return codes; therefore, the range for return codes is limited to zero to 255.
