My mainframe IBM manuals use PL/I.
The early version(s) of the S/360 compilers were inefficient by
not using available hardware instructions, e.g., bit fiddling
doable with OI and NI was implemented as subroutine calls. And
similar to ForTran, each load module included almost the whole
subroutine library, thus wasting (then) valuable memory.
