Simple programming help with the Prime

[John R. Graham]

There are currently no functions callable from PPL that will manipulate the stack. However, parameters to programs can be pulled from the stack. The syntax on the entry line is

Code:

function_name(n)

where "n" is the number of arguments that should be popped off the stack and provided to the program. The return value from the program also ends up on the stack. If you want to return multiple values, the only option today is to return a list.

Lack of integration between PPL and the stack is somewhat dismaying to me. In addition, the fact that the type system can't determine on its own how many arguments to pop is yet another symptom of incomplete integration.
