There is a relationship between an OSAICC definition and VTAM if you want to
use that OSAICC session as an non-sna terminal.
You then need a VTAM non-SNA definition in your VTAM list.

I see at your RTK github you are only providing load modules. Is there any
chance you can you provide corresponding source for others to use as a model
for other applications (like Eric’s EZNOSQL)? The basic RTK setup really

There are several steps,
First you need to (in vtam via V NET,INACT,ID=) inactivate any cross domain and
CDRSC connections between that LPAR and everyone else, then you need to (in
JES) using the TSOCKET(name) command change it to connect=no. From that point

Does anyone have any sample rexx code or any logic that you can share with

Correct. Tony supplied what you need. A VTAM APL is for applications, like
CICS and TSO, or for things that emulate terminals in software running
under VTAM, like NetView Access or TPX. The OSA-ICC is, as far as VTAM is
concerned, nothing more than a hardware 3270; all of the TCP/IP magic is in
There's a TSO/E vector table that has the address of the REXX routines.
// get the address of the TSO/e vector table
CVT * cvt = *(( CVT ** ) CVTPTR);
TSVT * tsvt = cvt->cvttvt;
// IKJTSVT.H - TSO/E Vector Table mapping
//
// Contains addresses of branch entered routines and control
You don't need an APPL. You need an LBUILD:
LOCAL080 LBUILD

ICU1L088 LOCAL TERM=3277,CUADDR=088,ISTATUS=ACTIVE,MODETAB=ISTINCLM, X

IIRC I needed the entry R0 to get the address of IRXINIT so I could call it.

My advice is to write a command processor. As I said creating an LE environment
for each function call will result in terrible performance. I’ve done this many
times https://github.com/daveyc/RTK. The trick is to use CEEPIPI to create a
pre-initialised LE environment and hang the pointer in

@Peter, I went around on the R0 question here a couple of years ago.
- No, I don't think there is a reliable way to get the entry R13 from within
the C/C++ code. Obviously, if you could, then any other register is trivial.

Isn’t there is some C library function (maybe unique to XLC/C++) that lets you

is that not possible?
