Operand Descriptions
PIPE EXPOSE
COMMAND
Specifies that messages that are generated by the processing of a command in
a previous CORRCMD, NETVIEW, MVS, or VTAM stage is exposed before
being absorbed into the pipeline. It is an error to specify COMMAND unless a
previous CORRCMD, NETVIEW, or VTAM stage exists in the pipeline
specification. If more than one previous CORRCMD, NETVIEW, or VTAM
stage exists in the pipeline specification, then only the one nearest to the
EXPOSE stage is affected.
Use of the COMMAND option allows a NETVIEW stage to successfully
process command procedures that use TRAP MESSAGES (or &WAIT).
When COMMAND is specified, the effect of the EXPOSE stage occurs entirely
before the messages are absorbed into the pipeline. There is no further action
when the messages pass through EXPOSE at its position in the pipeline.
When COMMAND is specified, the command itself (command echo) is also
exposed.
COMMAND implies RESPECT.
