IBM had PL/I compilers for TOS, DOS, and OS on System/360, and for DOS/VS and OS/VS on System/370. If those weren't full implementations of the original spec, they were pretty close. IBM PL/I had a good number of what I call toxic language features, such as the DEFAULT statement (which was Fortran's IMPLICIT on steroids). Most PL/I shops had as part of their coding standards a set of language features banned from the code. The ANSI standard eliminated a lot of these, although it also threw out some useful features such as iSUB defining and by-name structure assignment. One of my favourite features was sterling pictures, with pounds, shillings, and pence fields (represented internally as a packed decimal value in pence). Sterling pictures weren't finally deprecated in the IBM PL/I compilers until 1979, IIRC. -Paul W,.
