Preferred calculator program language

[morex]

Hello:

I'm wondering what is the preferred calculator program language for the users of the forum

I have calculators with BASIC, Keystroke, FOCAL, RPL, etc.

But I preferred RPN/FOCAL the most. I found it very simple, and practical for short/medium programs. For example in university I have written programs to help solve recurrent problems in the middle of exams.

I found RPL is powerful but dificult to read.

Thats why now I think DM42 is the best calculator available.

What are your preferences?

Regards
