- The manuals that describe PL/x (and its dialects) are few.
-
- GC28-6784 - "Guide to PL/S II" was issued May 1974, and as far as I
- know, was never updated. The entire manual is only 53 pages long, and
- that includes the Contents, Index, Glossary and sample listings. If
- you knew PL/I, then with the help of this manual you could read most of
- the PL/S fiche sent with MVS.
-
- SC27-0446 - "Programming Language for Distributed Systems (PL/DS)
- Reference", issued in May 1979, defined the PL/DS lanaguage that was
- used on the IBM 8100 Information System. This language looked
- suspiciously like PL/S (or at least a derivative), and with this
- manual, the MVS fiche as samples, and a little imagination, one could
- get a good feel as to just what PL/S really offered, even without
- a real reference to the mainframe version of PL/S
-
- I would like to see IBM issue a new PL/S language reference manual, if
- only because it would be easier to read those fiche. I would also like
- the opportunity to write and update code in PL/S, if that is the
- language the operating system is written in and its as good as IBM says
- it is. If PL/S had been offered as a product two decades ago it could
- have been a real productivity enhancer for all systems programming
- teams (and not just IBMs), and I am sure it would have been used to
- provide better function to many. Unfortunately, PL/S was caught
- somewhere between the issues of competitive advantage and the IBM
- vision that did not include customers writing and modifing operating
- systems, and PL/S never made it out the door. PL/S may be a great
- systems programming language, but at this point, I don't think anyone
- (other than IBM itself) would choose to start a major new project using
- it even if it was available (which I personally don't believe will ever
- happen). The holy grail of languages this year is C (or C++). Even
- IBM itself is starting to consider using languages other than PL/S for
- new projects.
