Structured assembly language for the IBM 360 and IBM 370, with a few high-level constructs. Syntactically it resembles ALGOL 60. Its grammar is defined entirely by operator precedence.

language A high-level machine-oriented language for the PDP-11 developed by R.D. Russell of CERN in Nov 1971. It is similar to PL360 and is written in Fortran IV and cross-compiled on other machines. (1995-01-05)
language A PL/I-like system language for the Honeywell operating system, CP-6. (1995-01-05)
An ALGOL-like assembly language for the DDP-516, similar to PL360. [“PL 516, An ALGOL-like Assembly Language for the DDP-516”, B.A. Wichmann, Natl Phys Lab UK, Report CCU 9, 1970]. (1995-01-05)
A systems dialect of PL/I, developed originally for the IBM 801 RISC minicomputer, later used internally for IBM RT and R/6000 development. [“An Overview of the PL.8 Compiler”, M. Auslander et al, Proc SIGPLAN ’82 Symp on Compiler Writing]. (1995-01-05)
