Hi Michael,
not knowing Object Pascal, I am not sure whether an Apache BSF (Bean Scripting Framework) engine
exists for it or not. If they have a BSF engine, then you should be able to use it via
BSF4ooRexx850. As such an engine would be an interface between Java and Object Pascal, you need to
adjust the environment for Java such that Java can find the Object Pascal BSF engine. But first make
sure, that this BSF engine for Object Pascal exists and is operable stand-alone.
It seems from your information that an Object Pascal REXXSAA interface exists, then it should work
with ooRexx, but you would need to try it out.
Ad the new ooRexx C++ interface: this is meant if you were to write a new native interface between
Object Pascal and ooRexx.
Good luck with your project and let us know how it goes!
HTH

I am seeking feedback / input on integrating ooRexx with Object Pascal via Lazarus from Free

Without BSF available for Object Pascal, would that mean the integration would only be via the
traditional 2.3.3. The RexxStart Function? (At least I have not heard around the Object Pascal
community talk of integration with BSF. I will specifically check.)
If that is the level of integration possible, then knowing that, I would next seek to learn how
to code Object Pascal to leverage a C/C++ API.
You can use the classic SAA interface, however you can use the much more powerful new ooRexx
APIs, which I would strongly suggest you to take advantage of.
hhhmmmm..... so you are making it sound like there are actually three
interfaces...
1) Classic SAA
2) BSF4ooRexx
3) More Powerful new ooRexx API's
Skim over the book "rexxapi.pdf" ("Open Object Rexx, Application Programming Interfaces") and
then check out all the samples in "samples\api".
Good luck for the project!
Thank you.
I found when I next researched how to do it from the Lazarus / Open Pascal side, there already is
a Classic SAA interface developed! :-) Huge bonus!

REXX
REXX is a programming language originally developed by IBM and over time included in all IBM
operating systems (e.g. OS/2, AIX and PC DOS). In addition to this, various IBM and non-IBM
implementations have been made available for most operating systems/environments (including free
implementations for Win32/Win64, Linux, Mac OS X, Solaris and many others - e.g. Regina, Open
Object Rexx). This interface unit makes it possible to inter-mix code written in Pascal with REXX.
Here is the readme from the extension available:
Hi/2.
This is REXX SAA interface. Nothing specific for this library. Only one thing:
This interface can be easely adapted to be used also for other OSes, not only
for OS/2. Look at Regina REXX for more info. As I know, early Regina REXX was
distributed with Win32 SDK.
About Amiga REXX. According to REXX unit source from FPC CVS tree Amiga rexx
not seems to be SAA compatible. Most portable solution is Regina REXX because
Regina supports SAA API.
Regina REXX ports available for OS/2, Win32, Unix, Amiga, QNX, BeOS & DOS.
Documentation
-------------
1. OS/2 Procedures Language 2/REXX online book
2. OS/2 Procedures Language 2/REXX Reference
3. OS/2 Procedures Language 2/REXX User Guide
Other books also available (for example, Regina REXX contains good
documentation)

So what more beyond the Classic SAA is available now without having to go all the way to full BSF
integration?
I am thankful,
Michael
