Preferred calculator program language

[HP67]

I don't have a Prime so I haven't seen the language it uses.

I like RPL much better than keystroke programming but it is an exercise in hurting yourself. It just feels good when it works but it's painful to change anything. Still, having a FORTH-like language on a calculator is great.

I would like to try Saturn ASM and ARM ASM on my 50g but I haven't had time. Too many other projects and interests. Haven't seen any threads on this in many years.
