     Judging from the name, it's probably something like

     swap23 == [swap] dip.

    In other words, hold the top of stack aside while we swap the next 2 items.

     Judging from the name, it's probably something like

     swap23 == [swap] dip.

    In other words, hold the top of stack aside while we swap the next 2 items.

         in other words, swapd.

         it appears that the definition of 'times' has also

         changed in the course of manfred's work (the manual

         reverses the stack order of the examples in several

         of the papers.)

         it would be good to have simple examples of all the

         primitives (condlinrec gave me considerable trouble).

         any word on the state of 'the joy of programming'?

         judging from the papers, this is going to be an

         indispensable book.
