But probably a type that stuck.

ILE COBOL uses QCBLLESRC by default. QLBLSRC is for OPM programs as is QCBLSRC although there is no reason they cannot be used for ILE source. QLBLSRC is for COBOL/400. QCBLSRC is for S/38-compatible COBOL.

The likely reason is:
LB is the prefix assigned to the COBOL development group (like MH for Message Handler, or SY for Security) for COBOL/400. The prefix is used in the object naming convention. Note that the CPP for CRTCBLPGM is QLBCBL and all the objects in the QLBL library related to COBOL have QLB (or some minor variant) as the prefix.

The prefix for S/38 COBOL is/was CB. Perhaps in the move to COBOL/400 a blanket rename was performed thus changing QCBLSRC (S/38) into QLBLSRC (AS/400)? Or perhaps they thought all objects in the product had to use the new prefix?

I suspect what they should have done was rename the S/38 COBOL compiler library to QCBL38 instead of leaving it as QCBL. This would have allowed them to keep QCBL for COBOL/400. Perhaps they thought that because the prefix had changed the library also had to change?

Didn't seem to bother the RPG team though. They used the same prefix for S/38 RPG and RPG/400 objects but added a suffix of 38 to all (well most of) the S/38 compatible objects.
