No, that is the website; this is a useful repository for finding old NetRexx versions online.

The NetRexx repo on GitHub is https://github.com/RexxLA/NetRexx <https://github.com/RexxLA/NetRexx> , stages are at https://github.com/RexxLA/NetRexx/tree/master/src/org/netrexx/njpipes/stages <https://github.com/RexxLA/NetRexx/tree/master/src/org/netrexx/njpipes/stages>

But I see you found the SourceForge repo.

Not at all: these are the included stages (‘programs’ I think the book calls them now) and show how things are done at the moment, but you can start a homegrown stage at literally any place on your file system.

I think this is about the minimal boilerplate:

import org.netrexx.njpipes.pipes.

class bagvendt extends stage

method run()

   loop forever
      line = Rexx peekto()
      output(line.reverse())
      readto()
   catch StageError
      rc = rc()
   end -- loop forever
   exit(rc*(rc<>12))
   
Best regards,

René.
