The following link https://www.ibm.com/docs/en/db2/11.5?topic=hvic-null-indicator-variables-null-truncation-indicator-variable-tables-in-cobol indicates that the null indicator should be defined as COMP-5.
At the same time, this link https://www.tutorialspoint.com/how-does-dclgen-utility-accommodate-null-host-variable-for-varchar-n-data-type#:~:text=The%20NULL%20indicator%20is%20a,PIC%20S9(4)%20COMP.&text=01%20ORDER%2DDESCRIPTION%2049%20ORDER,DATA%20PIC%20X(50). (granted, not IBM) indicates that COMP (which I've always used is okay as well.
If the second line doesn't work, google "cobol sql null indicators" and you should find it

Which is it?

COMP-5 is the same as COMP, except when the value exceeds the picture size. The compiler option TRUNC(BIN) will cause COMP to work the same as COMP-5.
