Hi: Can any one please tell me how to i change 00032 value in the
string without disturbing the original size of the string?

the second curly bracket upto the starting character "O"is always same
in the string

20070302
HD000000000{000000000{00032ODSS                                HCS1

newvalue=65
so it will be
20070302
HD000000000{000000000{00065ODSS                                HCS1

Thanks.
