It would do a job, but not the job that the OP requested. I'd probably
use IEBUPDTE rather than IEBGENER, but those scars have mostly healed.

Re: Inline Rexx in JCL?

[Phil Smith III]

So it appears the app that's calling the EXEC as an exit is doing some magic
of its own, I guess, since it works without the IRXJCL hack. And I didn't
post the example because it's called as an exit and thus it didn't seem
relevant (although if I had, y'all would have surely seen the dumb error I'd
made!). But I still appreciate the various advice.

...phsiii

P.S. Yes, UrbanDictionary is correct. Though that was part of my vocabulary
long before UD existed.

Here is one alternative...Incidentally, you don't need the DD DATA if you
start the /* REXX */ comment in a column other than 1.
*don*

//*
//* This JCL demonstrates how to create and execute an in-stream
//* REXX procedure. The PARM field contains only a single x'00'.

//STEP0020  EXEC  PGM=IRXJCL,PARM=' '
//SYSTSPRT  DD  SYSOUT=*

//SYSEXEC   DD  *
say "Hello world! Date = "date()", time = "time()
EXIT
/*
//*

If you don't want to use IRXJCL, but want to use TSO instead, you can do
something like this:
//*
//* This JCL demonstrates how to create and execute an in-stream

//*
//STEP0020  EXEC  PGM=IKJEFT1B
//SYSEXEC   DD  UNIT=SYSALLDA,SPACE=(80,(5,1)),

/*
//*
//SYSTSPRT  DD  SYSOUT=*

I'm 99 44/100 % sure that it's not the keyboard, but some silly-assed

Perhaps if you had given the OP's question even a cursory reading,
you would have noticed "inline" both in the Subject: and in the
body which you quoted.  I suspect the JCL manuals contain ample
descriptions of what "inline" means (although they may use "instream"
instead, which I suppose might excuse your misunderstanding).

(Of course, the OP could have helped you by supplying his example.)

Yes.  You're not allowed to do that.  Sucks, since the API to Rexx supports
either PDS members or PS data sets.

Are you using IRXJCL or IKJEFT??

Someone has reported a hack; apparently an unintended but sometimes
useful behavior.  If you supply:

//STEP  EXEC  PGM=IRXJCL,PARM='x arg1 ...'

(but you need to put actual NULs in the PARM with, e.g. PDF "HEX ON")
the JFCB (whatever) will contain zero in the member field, and SYSEXEC
will be opened as sequential.

Such a kludge should be neither tolerated nor required.

YMMV,

And you don't even need the leading /* REXX */ on the Rexx, which avoids
some hassles with EOD.

Re: Inline Rexx in JCL?

[Jonathan Goossen]

SYSEXEC is supposed to be a concatenation of libraries. The best that I 
can think of is something that I have done in other contexts. Put a step 
in front of it that copies the REXX statements into a temporary library.

I haven't done it, but you might be able to invoke edit to IKJEFT01 to put 
the code into a defaulted member of the library attached to the SYSEXEC. 
It would take one member of a library, but the code executed could be 
changed with each run.

Thank you and have a Terrific day!

Re: Inline Rexx in JCL?

JFC. Looking at it for the 10,000 time, I realized I had another DD
statement between the //SYSEXEC DD * and the Rexx code. What a maroon.

Thanks for trying it, Roger, and thanks to Alan Starr for his off-list
suggestions. It was when I went to change to a standalone, non-PO Rexx
program as a test that I realized my error. (And no, Rexx doesn't have to be
PO.)

Anyone ever gotten inline Rexx to work from JCL? I have a program that

be able to just do a //SYSEXEC DD * and go from there. Alas, I get:

IRX0110I The REXX exec cannot be interpreted. 

IRX0112I The REXX exec cannot be loaded.

(in that order, which is interesting). The IRXLOAD seems to get RC=0, but
the first call to the exit (IRXEXEC) gets RC=20.
