I wish I had an ‘unsound’ button.
No, SORT is right.
In this case, as remarked in the source, you have to run java testpipe - works here.

Colins analysis that the NetRexx compiler cannot handle this is correct. If you can include a version of the source that does not include | (pipes) at the start I can easier check that for you.
