List commands and functions in HP program language

[Tim Wessman]

As for the reasoning as to why it only works once inside a variable, how would one distinguish between "multiply your list times a number" {1,2,3,4,5}*(4) and "get the 4th item in the list" {1,2,3,4,5}(4)?

When it has a name it then becomes a named setter/getter function internally.
