Just a quicky

I am looking at the possiblity of reading a db2 table for a financial app
using cobol,  can I go above the PIC S9(19) COMP as I need to handle large
precision numbers (up to 31 digit).

The data would be stored as decimal in db2, i believe there is a compiler
option but cant find it in my documenetation

Any help greatly recieved
