Panamatik new ACT: difference between program meomory and library?

[Harald]

Now that I started playing with my new HP67E, I already came up with a question:

What is the difference between the program memory and the program library?

On page 73 of the ACT Manual (V1.06) I found this:


And on page 83 the key sequneces:


So, the way I would understand this is:
a) The 67 can only store 10 programs, all of them in program memory.
b) The others can store more, 10 in program memory, the rest in the program library. This makes sense as the 67 programs are much larger.

But I still don't understand the difference between program memory and library. I was wondering if it is just the way they are accsessed. But that doesn't make sense, as the 67 has key sequneces to access both memory and library.

I sent a propram collection via programing cable and it ended up in program memory. Works very nicely by the way!

Cheers,
Harald
