That System RPL word is called "MakeDirLabel". Its address in the 50g is #2E1EBh.

CASDIR is a folder containing the system variables used by the built-in CAS system. Its purpose and its contents are all described on page 4-1 and Appendix D of the HP 50g Advanced Users Reference Manual. Yes, it is automatically created by a master reset (ON+A+F, NO), but a far less destructive way to rebuild a mangled CASDIR is to execute the CASCFG command.
