Thanks for the help.

Chapter 3 "Objects and Execution" in Bill Wickes book "HP 48 Insights - Part 1: Principles and programming (G/GX edition)" should provide you some of the rationals for the current implementation, and the difference between execution and evaluation (section 3.3).

In particular, from section 3.5.2 page 53:

Quote: The ability of algebraic objects to act as data when executed, or as programs when evaluated, is one of the foundations of the HP 48's ability to perform symbolic mathematics.

A lot of thought has been put in the HP RPL implementation and I would be very cautious when deciding for a different implementation.
