IBM Tivoli NetView for z/OS Programming: Pipes - IBM notice

Usage Notes
PIPE CORRCMD
Usage note: Commands queued to the task running the pipe (such as with a
null label) are run at high priority because they must interrupt the
pipe itself. Therefore, subsequent commands invoked using the
same CORRCMD pipe stage (when the CORRCMD stage is not a
first stage) might interrupt previous commands. If command
procedures are queued by the CORRCMD stage using a null label
and if any procedure invokes the UNIQUE command, then one or
more procedures can be unexpectedly affected by the UNIQUE
processing. See the description of the UNIQUE command in the
IBM Tivoli NetView for z/OS Customization Guide for more
information.
cmdtext
Specifies the command to be processed. If cmdtext consists of a label only and
CORRCMD is not the first stage, then CORRCMD routes commands in the
input stream as specified by the label. Such commands cannot contain a form
feed character ('OC'X) unless the command being routed is PIPE.
Note: A PIPE command can contain any character. If your command contains
the form feed character ('OC'X), embed the command in a PIPE. For
example,
yourlabel: PIPE CORRCMD cmd with
possible ff chars | CONS ONLY
CGI
Use the CGI option for a command that is able to produce either a 3270
display or HTML, to inform the command that HTML is preferred. The direct
effect of the CGI option is on the REXX function, CGI(), and causes the
function to return a value of 1. CGI cannot be specified with ECHO.
ECHO
When ECHO is specified, the text of the command itself is written to the
pipeline before the command is executed. ECHO cannot be specified with CGI.
MOE
Message on error (MOE) examines the return code from the stage. If the return
code is not zero, it inserts message DWO369I containing the return code into
the stream after any messages the stage might have returned. The return codes
in the message are from either the command or the implied wait. If you do not
specify MOE, return codes from stages are ignored.
NOPANEL
When NOPANEL is specified, the stage is not allowed to display a full-screen
panel. If it attempts to do so, message BNH113W is inserted into the pipeline
and the stage receives an I/O error code from NetView presentation services.
number
Optional first argument is a timeout override.
If the first token following CORRCMD is numeric, it is interpreted as a new
specification of timeout which overrides the value specified for the stage by
CCDEF. Valid values are 1-10000000. The default value is 60, unless another
value is defined with CCDEF.
v The timeouts and termination conditions to be used are defined by the customer
using the CCDEF stage.
