I don't see the problem.

EXECIO DISKR ddn1 1 '(' STEM foo.

As mentioned above, EXECIO is part of TSO REXX.
The problem is not EXECIO but with reading the records of a dataset
assigned to an arbitrary DDNAME passed as a parm to REXX.
Consider the folowing:
//*********************************************************************
//* NOTE: 'U' => TSO USERID(S); SPECIFY LIST OF USERIDS UNDER DESTIDS *
//* ¯¯¯¯¯ 'C' -> CONSOLE; SPECIFY MASTER ETC. UNDER CONSIDS *
//* *
//* 04/01/95 CMP *
//*********************************************************************
//*
//CLIST EXEC PGM=IKJEFT01,
// REGION=512K,
//* PARM='%TSOSEND DESTIDS SYSIN USERID' (DESTLIST=DESTIDS)
// PARM='%TSOSEND CONSIDS SYSIN CONSOLE' (DESTLIST=CONSIDS)
//*
//SYSPROC DD DISP=SHR,DSN=<Clist dataset>
//SYSTSIN DD DUMMY
//SYSTSPRT DD SYSOUT=*
//CONSIDS DD *
<master console ID>
//*
//SYSIN DD * (all messages below are sent to the console)
Dear MVS OPS,
Could someone please start DMSAR on LPAR1 and LPAR2 so my job can
restore datasets from pseudo-volume <whatever>? It's been waiting
for 2 1/2 hours.
Here's part of the joblog (jobname on LPAR1):
14.58.46 JOB15032 ---- <whenever> ----
14.58.46 JOB15032 <whatever>
14.58.46 JOB15032 <whatever>
16.00.08 JOB15032 MSG FROM OPER: '***********************************
16.00.08 JOB15032 MSG FROM OPER: '* THIS JOB IS BEING AUTOMATICALLY C
16.00.08 JOB15032 MSG FROM OPER: '* BEEN RUNNING IN A CLASS ID INITIA

16.45.05 JOB15032 MSG FROM OPER: '***********************************

Thanks a lot.

Which is quicker - manually issuing 'oodles' of TSOSENDs (1 per message
line) to the console, or sending all messages together via SYSIN?
That's why I used Clist for that <grin>.
