I'd have to disagree with the other poster James. Writing a programs to
read and write stream files is really not very difficult, and it can
provide significant benefits over CPY*IMPF and iSeries Access File transfer.

I am comfortable using the System API's to create files on the IFS, but have not had to read them.
You can use the read() API to read a stream file. See
http://www.scottklement.com/rpg/ifs_ebook/basics.html#OPENCLOSE.
Start with that, and come back if you have more questions. Generally
speaking, I'd say:
1. Figure out how to read data from a string file in chunks of n bytes
(reading one byte at a time is inefficient).
2. Now forget that the data came from a file and process it byte by byte
the same as you would process multi-field data from any other source.
Scott's ebook should give you all you need, but feel free to ask more
questions here. Many questions will already be answered in the archives
of this list.
