I am waiting for the LUA4Z.LOADLIB to be added to linklist.
I do not have access to the ISPF command tables.
HOWEVER,
This job worked in batch.
I put the LUACONF member in LUA4Z.SAMPLIB and ran this:
//LUA EXEC PGM=LUA,PARM=IVP
//STEPLIB DD DSN=XCICS.LUA4Z.LOADLIB,DISP=SHR
//*UA DD DSN=XCICS.LUA4Z.CONF,DISP=SHR

A TSO call will not do the trick. You have to use the Lua launcher. The SAMPLIB
contains a ready to go ISPF command table to put into USRxCMDS or SITECMDS etc.
To invoke Lua try the following:
If you have installed the command table into your ISPTLIB then simply:
LUA IVP
otherwise, If you have allocated the LUA DD then:
TSO LUA IVP
if the LUA DD is not allocated you can specify the qualifieid data set:
TSO LUA "//'XCICS.LUA4Z.SAMPLIB(IVP)'"

Nope! The DD should be LUA and the member name should be LUACONF.

Thanks again for the info. I will try to do without linklist for now.
I tried to set up the LUACONF member as documented and get this error:

Unfortunately that's not possible. Lua4z is a C/C++ XPLINK application and it
requires a PO library so a PDSE is mandatory.
I understand your position but XPLINK is the build and it results in much
faster code. I know you probably already know this but you can always
dynamically add a PDSE to the linklist.

Here is another thing I never saw before.
I do not have a PDSE in linklist (that I can use) so I am trying to copy the
LUA4Z.LOADLIB modules into a regular pds and get this error.
I do not want to have another linklist lib added for this product and was
always able to copy PDSE load modules into PDS's.
Is there any way to copy the LUA4Z.LOADLIB modules into a regular PDS?

You need to enter the y in lower case - otherwise those dataset errors occur.
I have now changed the installation script to fold all input to upper case.
I am not up to snuff on UNIX lately and do not understand what the ? in the
environment variables mean.
They did work when I added them to my profile, but I never saw this syntax
before:
export LUA_PATH="./?.lua;\
$LUA_HOME/share/lua/5.1/?.lua;\
$LUA_HOME/share/lua/5.1/?/init.lua;\
$LUA_HOME/lib/lua/5.1/?.lua;\
$LUA_HOME/lib/lua/5.1/?/init.lua;\
//DD:LUA(?)"
The ? is a placeholder for the module name. So if you do the
following
local m = require "test" it will replace "?" with "test" in the search path.
The //DD:LUA(?) will resolve to //DD:LUA(TEST) so if you are running in TSO or batch it will load the module
for a PDS(E) allocated to a DDname of LUA.
If you are running native then my suggestion is to set LUA_HOME in the LUACONF
member to make your life easier http://lua4z.com/doc/manual/install.md.html.

Well, I got it installed. I ran into a "problem" with the
./lua4z-1.0.0.bin when I ran it a second time. The first time, it
said it couldn't find the PDSEs (LOADLIB and SAMPLIB) and did I
want to define them? All is good. I reply "Y" and they are allocated.
When I ran the script a second time, it did the same. It did _not_
properly detect that the PDSEs existed. It tried to allocate them
again, and I got error messages from that allocation. The script continued to
run.
All in all, I got what I needed, but it seems to point out a
problem with the installation script. Oh, I entered the data set
names in lower case, which might be the problem.
Many thanks for testing this John. Good catch!
The lua4z/examples/ivp.lua fails when I run it from my UNIX shell.

I looked at the ivp.lua. It references a variable "modules" which
contains "cjson" and "socket". There exists an cjson.so in the
LUA_CPATH. But "socket" is a directory in /HM/lua4z/lib/lua/5.1, not an ".so"
file.
Granted, I need to read up on lua, but given the results, this
seems like it may be a problem in the ivp.lua script.
Minor nits, but thought I'd give you a heads up.
Can I convince you to try it again. I've uploaded an updated IVP.
