IPL is one of several IBM-isms.  A few others:

main storage = memory.  IBM considered "memory" too anthropomorphic.

DASD = direct access storage device = disk.  This is a hold-over from
the days when, in addition to disks, there were drums and the IBM 2321
data cell drive (aka the noodle-picker).  DECtape would probably be
classified as DASD.
