Newbie Questions

[The Shadow]

Hello, I'm a HP calc user from way back. Can't afford the physical Prime just now, but I've been messing around a fair bit with the emulator... and in the process have gathered some questions.

1. Is there any way for a program to return more than one value to the stack in RPN entry mode? I'm not seeing one, but maybe I'm missing it.

If not, a suggestion might be to add two new commands: One to turn the RPN stack into a list, and vice versa. Then it would be easy to add as many things to the list as you like, then transform it.

Or even just re-add the DEPTH, ->LIST, and LIST-> commands. (A version of EXPR that works nicely with RPN would be wonderful too, but let's not get too greedy. :)

2. Is there any way to retrieve the number of arguments a program is expecting?

3. Is there any equivalent for the old KEYEVAL command? (For those who might not know, it simulates the press of a particular key.) Key reassignment really comes into its own with this ability.

4. How would one go about storing a value in a variable name INPUT'ed by the user? Is this even possible?

5. How does one insert a line feed? I can't find it in the CHARS menu.

There will probably be more later, but that'll do for now! Thanks in advance for your help. Oh, and I guess there's one more:

6. Any plans to make another calculator that's basically the 50g with the Prime hardware and the new Prime commands? 'Cause I will break the sound barrier ordering one if so. :)
