I have a pipe that takes two input streams and passes them through a set of standard and custom stages to produce an annotated list of significant differences between them.
One of the new stages called from the differencing stage takes a large static file as input and applies some changes to the output data. But as it is as the moment it rereads and reprocesses this file for each record, which clearly needs to be changed. What's the best way of setting up a parallel pipe which only needs to be initialised once and then sending and receiving records from that in the middle of a rexx stage? (Addpipe by chance? I can't find too much documentation on how to use it, and what I can seems to fit it on to the start or end of an existing pipe, not something that can be called in the middle. Any thoughts welcome. ian ... Ian S.
