Convert Char string with Sign to Decimal in DB2

[ramanivx]

I need to convert a character string using DB2 SQL into a decimal (11,2). This character string has a sign also. I tried using Decimal verb and it gives ++++++++ sign after converting.
Appreciate help.

Example
input:
SUBSTR SUBSTR
110006 0000000000{
110011 0000000000{
110016 0000000000{
110020 0000000893H
110071 0000000000{

Query:
select substr(varlenfld, 18, 13),
decimal(substr(varlenfld,229,11),11,2) from
library/filename f

output:
SUBSTR DECIMAL
110006 +++++++++++++++
110011 +++++++++++++++
110016 +++++++++++++++
110020 +++++++++++++++
110071 +++++++++++++++

I think it is possible to code but it is tedious to convert the last character into a hexa using a function in DB2. Can anyone help me come up with a hexa table for all the last characters. BTW, is there any better way in DB2 SQL?
