There is some access through the PPL function parameter and return value mechanisms. For example,
This program pops two values off of the stack, which end up in the variables X and Y, operates on those variables and returns the result, which is then pushed back onto the stack.

However, there's no ability to arbitrarily manipulate the stack outside the parameter / return mechanism. This is a capability I would sorely like to be added to the Prime: the stack needs to be a first-class citizen across the calculator.
