RE: prevent list evaluation
So the the cas command line parser thinks a list is not just a collection of objects (which it should be) but something with semantic meaning. (i dont know what that is)
But it is bent on evaluating all the elements in it .

I dont know much about xcas

So my function rcl ('a') does the job nicely.

In rpl a stored list is not a program , but a data structure.
There are also functions to evaluate element by element but its not automatic.


A deeper flaw in ppl is the inability to nest blocks (and create locals)
so it is not like any other language i know . Definitly not lisp,c,pascal,etc.

I thought at first i might be able translate rpl to ppl (since i can now write programs
from a program). But alas ppl is a weaker language than rpl.

At this point my prime sysrpl emulator runs abot 10 times faster than on my hp50
emulator.

Both Prime and HP50 Are running on Samsung Tab pro.

There is a template for a block so i thought maybe it would work. But no.

I work with android Prime only for now on my
Galaxy Tab Pro/Note 2
