Pipes wasn't a thing until v7.something or other. A bunch of lexical functions weren't implemented until then too.

  Pipes very much existed before v7. At a bare minimum they're in v6 as I remember them from Lyon's, but I think they were as far back as v3.

    Yeah, sure...from § 11.13.2 of TFM[1]: > In OpenVMS Version 7.1, the DCL PIPE command was introduced. Ask me how I really know OpenVMS v6 doesn't have pipes.

      I thought you were talking about Unix, hence my Lyon's comment.

        I thought the GP's context made that clear, but fair enough.
