Looks like DESC code 11 on the WTO macro would work;
DESC=(descriptor code...) Specifies one or more descriptor codes as
decimal numbers in the range 1-16. Codes 1 to 6, 11 and 12 are mutually
exclusive. If more
than one of these codes are specified, the most significant one is
used (see below), the others are ignored. Code 7 can be assigned in
combination with any
other code. When DESC is omitted, a descriptor code of 7 is
assumed. DESC is ignored if specified together with CONNECT (see below).
Descriptor codes determine, along with other factors, the
presentation and retention attributes of a message. The meaning
associated with each descriptor code
is as follows:
1 System Failure: The message indicates an error that disrupts
system operations. To continue, the operator may have to re-IPL the
system or restart a major
subsystem.
2 Immediate Action Required: The message indicates that the
operator must perform an action immediately. Some tasks may be in a wait
state until the action is
performed, and system performance is affected.
3 Eventual Action Required: The message indicates that the
operator must perform an action eventually. No tasks are waiting for
action completion.
4 System Status: The message indicates the status of a system
task or of a hardware unit.
5 Immediate Command Response: The message is issued as a
response to a system command.
6 Job Status: The message indicates the status of a job or job
step.
7 Task-Related: The message is related to the processing of an
application or system program and is automatically DOMed by the system
when the related job
step ends after logging, if applicable.
This descriptor code is assigned automatically when the
message is issued by a user task on its own behalf.
8-10 Not used by z/VSE, ignored when specified.
11 Critical Eventual Action Required: The message indicates that
the operator must perform an action eventually, and no tasks are waiting
for action completion.
However, the action is important enough for retaining the
message on the console screen until the action is completed.
12 Important Information: The message contains important
information that must be displayed at a console, but does not require
any action in response.
13-16 Reserved.

Here's hoping someone can help me out so I don't have to
research how this works. We have an RPG-II batch program which invokes
an assembler routine both for file SPECIAL I/O and via the EXIT opcode.
When this program has a particular file open in update mode, the
assembler routine puts a message on the console which is both
highlighted and held to prevent it scrolling off the screen. At the end
of the program the message is unhighlighted and unheld. The following
is the calling code:
ISOPEN MVI FSTSW,C'O' FILE STATUS
SWITCH
MVI WRTKEY,X'00'
MVC WRTKEY+1(63),WRTKEY
MVI CNSLTXT,C' '
MVC CNSLTXT+1(42),CNSLTXT
MVC CNSLTXT(20),=C'FILE - XXXXXXX OPEN.'
MVC CNSLTXT+7(7),FILNM
LA XR4,CNSLMSG
LA XR5,50
BAL XR11,CNSOT
B GOOD
...and the following is the console subroutine and
storage definitions. I don't see where the assembler code makes any
distinction regarding highlighting and holding. Hints? Thanks.
