The change request system used the SCCS MR to create named change sets, tied into the IMR (initial modification request) system which had purely numeric identifiers. An MR name was created with subsystem prefix, IMR number, MR sequence characters, and a character for the release or "load". So, for the gr (generic retrofit) subsystem, the first MR created for the 2371242 IMR, destined for the 'F' load, would be gr2371242aF.
