We have huge data files with a data field PIC 9(2) defined in the primary key (it is a counter). Until now, there was no need for values > 99. But now we are facing a situation with a need for larger values > 99.
How can we change the data type and keep the original information and record size?
We tried by changing the PIC 9(2) to PIC 9(2) USAGE IS COMP-1 but the original values somehow changed: new_value = old_value 12336 e.g if old_value = 1 then new_value = 12337
