Thanks for the explanation about the ?s but I still do not see what they are being used to substitute for. I passed the UNIX IVP test, but my profile contains this:

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. > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] > On Behalf Of David Crayford > Sent: Thursday, October 23, 2014 9:24 AM > To: IBM-MAIN@LISTSERV.UA.EDU > Subject: Re: [ANN] Lua4z: the Lua programming language on z/OS, with > batteries > > On 23/10/2014 8:42 PM, John McKown wrote: >> Well, I got it installed.
