        FREQUENTLY-ASKED QUESTIONS & ANSWERS
        ====================================

(Q1) What is PL/I?

     PL/I is a general-purpose programming language, which
     is used for solving problems in a variety of fields
     such as commerce, science (including mathematics,
     physics, chemistry), engineering (incl. civil, electrical,
     aeronautics), medicine and so on.  It can be used for
     system programming, and the facilitites are such that
     it is rarely if ever necessary to resort to machine-language
     or assembly-language programming to solve problems.

     It has more power than Pascal, Fortran 90, BASIC, C, and
     COBOL, and has comparable facilities to Ada.
     The main areas where PL/I is superior include interrupt
     handling, the built-in debugging aids, the macro
     processor facilities, string-handling and input-output
     (see below).

     The language has good documenting and self-documenting
     facilities;  programs are easy to read and to understand.
     It bears some resemblance to Fortran and BASIC.

     The language is suitable for beginners, as well as for
     anyone wanting to become a professional.

     An excellent summary of PL/I can be found at:

    (b) ordinals;
    (c) user-defined types;
    (d) Unsigned integer type;
    (e) New DO loop options that cause the loop to
        terminate without overrunning the limit (specifically
        for ordinals and unsigned integers);
    (f) A much-enhanced macro-processor.
    (this is not an exhaustive list)

    There are also 97 new built-in functions, including
    extra-special DATE/TIME functions, string-handling
    functions, housekeeping functions (e.g.,
    where-am-I-called-from?), and ordinal functions
    (including a function to supply the name of an ordinal!).

     *  Or consider attending a SHARE or GUIDE PL/I presentation
    as either a spectator or presenter.  Postings appear from
    time to time in comp.lang.pl1

(Q9) How did PL/I originate?

     PL/I came into being as a result of an attempt to produce
     a revision of FORTRAN.  Such were the changes necessary that
     it was not possible to introduce the new features needed
     to bring FORTRAN up-to-date, and to be compatible with
     existing programs, that it was decided to introduce a
     new language that included the best features of the
     then main languages FORTRAN, COBOL, and Algol.

     Originally, the new language was called "New Programming
     Language", or NPL.  However, as these initials were
     already taken by the National Physical Laboratory in
     Britain, the name became PL/I (for Programming Language One).

     The new language contained features not then seen before in
     a general-purpose programming language -- including interrupt
     handling, array operations, list processing, and a macro
     pre-processor.

     There is some controvesy over the name -- whether it is PL/I
     or PL/1.  The first manuals (for the first compiler, the
     IBM PL/I (F) compiler) called it PL/I, not PL/1. The ANSI
     standard calls it PL/I.  The title of the first reference
     manual is:
     IBM, "PL/I Language Reference", 1965.

     The title of the manual for the first compiler is:
     "IBM System 360 PL/I (F) Language Reference Manual", 1966.

     Since then, almost all manufacturers and textbooks
     called it PL/I.

(Q10) What tools are available?

Introducing Three New Products for Today's Programmer
-----------------------------------------------------
PL/I is well known as a powerful, proven language that was designed
with the programmer in mind.

Today's programmer is developing complex client/server applications.
Today's programmer is expected to be more productive; to write more
code in less time and to write better quality applications in the
most cost effective environment.

IBM introduces three new members of the PL/I Family that have been
designed with today's programmer in mind:  PL/I for OS/2 Professional
Edition, PL/I for OS/2 Toolkit.

Get Client-Server Right with PL/I
---------------------------------
If your company has a large inventory of PL/I applications, you are
probably looking for a way to take advantage of new technologies while
leveraging the investments you have already made.  Are you wondering
if there's a way to reduce your mainframe overhead and program more
productively, without compromising the power and flexibility that made
PL/I an excellent investment over the years?

PL/I for OS/2 Professional Edition and the PL/I for OS/2 Toolkit can
relieve your mainframe by letting you move your applications to a
powerful development environment on the PC.  The PL/I for OS/2
products provide a visual PM front-end for developing VSAM, DB2,
CICS, and IMS Client Server/2 applications.

Continue to use your PL/I expertise while optimizing for the creation
of database and transaction-driven applications that will execute on a
mainframe, as client/server applications, or on a stand-alone PC.


Benefit from the Ease of Use and Performance of OS/2
----------------------------------------------------
OS/2 has many powerful features that makes it an attractive environment
for PL/I development.  Here are just a few:

     - Ease of use through an object-oriented iconic "drag and drop"
       interface which makes OS/2 easy to learn and use
     - Performance that is predictable and consistent
     - True multithreading that lets you use multiple programs
       simultaneously
     - 32-bit addressability means you can tap the potential of today's
       advanced microprocessing technology

With these features, OS/2 can raise your computing capability to a whole
new level by allowing you to work quickly, easily, and intuitively.

PL/I takes advantage of these innovative features in OS/2.  The PL/I
for OS/2 products include header files that let you develop OS/2
Presentation Manager applications; a visual tool that generates PL/I
code as you 'paint' Presentation Manager applications, and PL/I supports
OS/2's multi-threading capability to further improve performance.

Together, PL/I and OS/2 provide you with a powerful, reliable
application development solution that increases your choices and
multiplies your opportunity to get bigger and better benefits from
your PL/I code and from your system.

Access DB2 with PL/I for OS/2
-----------------------------
If you depend on data stored in a DB2 database across multiple platforms,
you probably want to access it from your PL/I applications, whether they
are running on MVS or OS/2.

PL/I for OS/2 Professional Edition includes a preprocessor that supports
DB2/2 and lets you embed SQL statements in your PL/I programs.  If you
have a distributed database connected by DDCS/2, you can access data
stored in other DB2 products, from PL/I applications on OS/2.

You can now access DB2 data on multiple platforms from PL/I products on
multiple platforms.  PL/I's database solution lets you build new
client/server applications or extend the life of your existing mainframe
PL/I applications.


Develop CICS Applications in a Client/Server Environment
--------------------------------------------------------
CICS is the transaction management solution of choice for many
businesses.  If your company uses CICS for online transaction
processing, you can take advantage of the client/server support
provided by both CICS OS/2 and PL/I for OS/2 Professional Edition.

PL/I for OS/2 Professional Edition includes a CICS preprocessor that
lets you develop CICS applications on OS/2.  CICS OS/2 and PL/I
for OS/2 Professional Edition provide powerful facilities
for improving your productivity in the development and debugging
of new applications.  PL/I for OS/2 is a valuable tool for
development of CICS applications for running on CICS/VSE and
CICS/ESA systems.

The transaction management solution provided by CICS OS/2 and PL/I for
OS/2 Professional Edition lets you build new client/server applications
or extend the life of existing mainframe applications.


Use PL/I to Develop IMS Client Server/2 Applications
----------------------------------------------------
If you have IMS data or transactions on a mainframe, you can now
access them from applications written in a more productive
environment.

Using PL/I for OS/2 Professional Edition and IMS Client Server/2, you
can develop client/server applications that call IMS data or invoke
IMS transactions that are running on a mainframe.  By combining these
two products, you can access your mainframe IMS data and transactions
from a more flexible environment, while preserving data integrity.

Developing and maintaining applications that access mainframe IMS
can be very easy with PL/I.  You can develop graphics-based
applications with PL/I for OS/2 Professional Edition.  This simplifies
the process by letting programmers paint an application, therefore
automating the application development process.  Did you have any
idea IMS applications could be this easy to write?


Tailor PL/I for Your Organization
---------------------------------
PL/I is a powerful language that affords programmers a lot of
flexibility.  You can, for example, alter the severity of compiler
messages or suppress them completely.  When debugging your
program, you can get a listing of diagnostic messages that identify
errors in the source program. Your program listing can also
include an attribute and cross reference table which tells you not
only in which lines a variable is referenced, but also in which
lines it is altered.


Improve Your Productivity with PL/I for OS/2 and WorkFrame/2
------------------------------------------------------------
PL/I for OS/2 provides a cost effective visual desktop development and
test environment.  PL/I for OS/2 with WorkFrame/2, a GUI project
manager, makes application development simpler and more straight-
forward.  Using PL/I for OS/2 and Workframe/2 you can, for example,
set compiler and other options and link them to a specific program or
project for repeated use.  Using WorkFrame/2, you can also identify
and locate error messages and edit your source code without ever
leaving your work session.


Clean Up Your PL/I Applications with a Graphical Facility
---------------------------------------------------------
With PL/I for OS/2's powerful GUI debug facility, you can set change,
entry, or statement breakpoints.  Other debugging features
include the ability to trap conditions and monitor changes
in variables during execution of your program.


Benefit from New PL/I Language Features
---------------------------------------
The following is a list of some new language enhancements in the
PL/I for OS/2 products:
-- Strongly typed enumerations, typed structures and unions,
   and user-defined types make it easier for you to identify
   potential problems at compile time.

-- PL/I's various storage classes--including automatic,
   static, controlled, defined, and based--increase the
   flexibility of the language.

-- A choice of linkages and parameter-passing mechanisms
   lets you call C, C++, REXX, and Fortran applications from
   within your PL/I applications.

-- The new PACKAGE statement allows you to group
   related declarations and procedures that share name
   scope.

-- A state-of-the-art macro facility is now available in
   PL/I for OS/2.

-- With restricted expressions and named constants, you can

I don't think so.  At least not IBM's implementations.  It could be
that another company allows a numeric expression on a leave statement.
It would make maintenance a pain when a new loop was inserted.
Maybe BASIC allows this?

We promoting it for both legacy systems and new work.  IBM is using it
for our own development.  We delivered PL/I for OS/2 and are now
working on PL/I for AIX/UNIX.  We are also looking at OO PL/I but
I don't think that is as important as getting on other platforms.

As I do not know what Your specific need is, here are a quick list:

*  IBM   (e-mail: teampli @ vnet.ibm.com )

   It looks as they made big efforts in the new version for OS/2.
   I can't say more for the moment, have not OS2 loaded yet.

   Standalone version for some $ 200 [dont know exact amount].
   Fullblown version with DB2 and CICS, mainframe access and the lot
   for around $1000+.

*** Digital ( http://www.dec.com/home.html )

   Their PL/1 compiler on OpenVMS for VAX is very good. I have used
   since around 1982 in writing many system programming tools.
   And it generally saved me all the trouble of assembly language.

   It is also available for RISC Ultrix (and OpenVMS for Alpha I belive).

   IMHO, they make much to little advertisment about this jewel.

*** Liant  ( email: dickp @ lpi.liant.com )

   Versions for various versions of UNIX. Mature (version 5).
   Also claims to have versions for NT and MSDOS (anyone tried?).

   Seems somewhat expensive to starters but very able tool for
   doing migration with.

*** Others

   Data General had a compiler back in the early 80'ies. Lost track.
   Data Research hade a compiler for CP/M.
   Rumours is that Prime also had a compiler for Prime/OS.

There is a mailing list for PL/1 at LISTSERV @ vmd.cso.uiuc.edu

IBM have also lauched a newsletter called the PL/I Connection.
You call use the address above.

Please, keep in touch.
