Description


The ΠLIST command returns the product of all the elements in Ldata, i.e.: $$ \prod_{k=1}^{n}{data_{k}} $$ The list must not be empty and its elements must be suitable for mutual multiplication.

Compatibility


ΠLIST is not fully equivalent to its userRPL counterpart.

In particular:

  • in userRPL the list must contain at least two elements.
