Describe the bug

In Cloud Migration Project, Cobrix library is making null for the field when we get a value like '0000{' to the type PIC s9(5) in copybook for the US_ASCII file.
In the existing on-prem system it was making 0 and not giving null for the same value.
Could you please help us to solve this

Sample US_ASCII Data:
P0000{
T12340
P89870

CopyBook:
01 Employee.
05 EmployeeType PIC X(1).
05 Salary PIC S9(5).

Expected Output:
EmployeeType Salary
P 0
T 12340
P 89870
