WTB RPN Module for TI-59

[Thomas Klemm]

If anybody has this module I'd be interested to see the generated result.
As an example, here is a program for the HP-67 that calculates the greatest common denominator of two numbers:

Code:

001: 31 25 11 # LBL A
002: 35 33    # ST I
003: 35 53    # Rv
004: 31 25 00 # LBL 0
005: 41       # ENTER
006: 41       # ENTER
007: 35 34    # RC I
008: 31 51    # x=0
009: 22 01    # GTO 1
010: 81       # /
011: 31 83    # INT
012: 35 34    # RC I
013: 71       # *
014: 51       # -
015: 35 24    # x<>I
016: 22 00    # GTO 0
017: 31 25 01 # LBL 1
018: 35 53    # RC I
019: 35 22    # RTN

I don't have a TI-59 but here's an analogue program for the TI-57:

Code:

00  32 1  # STO 1
01  22    # x<>t
02  32 0  # STO 0
03  86 0  # Lbl 0
04  19    # C.t
05  33 1  # RCL 1
06  66    # x=t
07  51 1  # GTO 1
08  33 0  # RCL 0
09  45    # /
10  33 1  # RCL 1
11  85    # =
12  49    # Int
13  55    # *
14  33 1  # RCL 1
15  85    # =
16 -34 0  # INV SUM 0
17  33 0  # RCL 0
18  22    # x<>t
19  33 1  # RCL 1
20  32 0  # STO 0
21  22    # x<>t
22  32 1  # STO 1
23  51 0  # GTO 0
24  86 1  # Lbl 1
25  33 0  # RCL 0
26  81    # R/S
27  71    # RST

I just wonder how this translation even works.
Is the stack implemented using registers?
Does this mean that e.g. Rv is implemented using multiple register commands?
Are these inlined or are subroutines called?
I can imagine that correct but rather inefficient code is created.

OTOH it's possible to implement an Algebraic Operation System (AOS) using the HP-41C.
This simulates e.g. the TI-57 at least to some extent.
