Command Description
NetView Pipelines help you solve a complex problem by dividing it into a series of
smaller steps. Each step or stage solves one part of the overall problem. Some
stages read data from system sources, such as files on DASD or variables in
command procedures. Other stages filter and refine that data in some way. Still
other stages export (output) data from the pipeline. You can connect stages in
logical sequence until they collectively cover all steps required to solve your
problem.
You determine the function of each stage by coding a stage as described in this
chapter.
When you have completed a series of stage specifications, you can run them with
the PIPE command. The PIPE command identifies the series of stage specifications
you want to run and, through parameters, controls other run characteristics that
are described later. A series of stage specifications and the instructions for
connecting them is called a pipeline specification. A PIPE command containing
multiple pipeline specifications, labels, and end characters is called a complex
pipeline. Asimple pipeline contains a pipeline specification, but does not contain
labels or end characters.
You can obtain information about the PIPE command and stages using the
NetView online help facility. To display online help for the PIPE command, enter:
