Re: Communication between Python and ILE languages (was Node.js announcement)

Hi John,

My line of comments/questions was concerned about Python-to-RPG
communication at a high level. I do understand the os400.Program
implementation of calling RPG is different than XMLSERVICE.

Thanks for the links.

I can further review?

Well, I'm certainly glad to put aside any competition among languages.
But I am still getting the strong sense that one or both of us is not
understanding the other.

It sounds to me like the Ruby gem you're talking about is the Ruby
client for XMLSERVICE. If that's the case, then no, there is no
existing Python equivalent.

The facility that I mentioned, os400.Program, is bundled with
iSeriesPython (so effectively part of its standard library). It's
implemented in ILE C and very specific to iSeriesPython. It really is
just a thin wrapper over the operating system's call mechanism (it's
almost exactly equivalent to RPG's CALL opcode). Once you start
talking about servers or services, you are in a completely different
league.

But you want a link for review, so

http://www.iseriespython.com/app/ispMain.py/Start?job=os400page
http://sourceforge.net/projects/iseriespython/files/Source/2.7/

Note that the documentation on the Web is quite sparse and quite out
of date. It doesn't mention things such as the 'b' type for "raw
binary strings" (not converted to and from UTF-8) or 'p' for pointer.

os400.Program is ultimately the foundation for api2.py, which is a
package for working with IBM i system APIs using iSeriesPython:
