I'm trying to move beyond apprentice plumbing and develop some
journeyman skills. I've mastered the built in stages, mutistreaming and
heavy spec manipulation. But I find myself ending a pipe, saving the
stream to disk, and dropping back into rexx to do things. What is the
proper way, based on data flowing through a pipe, to manipulate the
environment outside the pipe, using things such as CP and CMS commands,
while keeping the records flowing? For example, TAPE manipulation,
LINKing disks, setting up the device you're going to drive, etc. I've
looked through the Author's Edition, but can't really figure it out. Is
there some tutorial material somewhere that would help?
