You should find there more details about the inputs/outputs of the functions.

Line 37 (=RCL M) is between the end of the LW (RTN) and the beginning of LWM so I suppose it’s there to calculate LWM(x) just after LW(x) by simply pressing R/S.

Thanks. Make sense especially for a debugging.
I moved in-between to a HP41CX and confirm both script for infinite tetration have the same result (that was the expectation):
- above RPN (see attachment) with series; called "TETS" a bit like "TETration infinite Series" (takes.. long..)
- below with lambert WL0 from SANDMATH; called "TETL" a bit like "TETration infinite Lambert"

Quote: 01*LBL "TETL"
02 ENTER^
03 1/X
04 Y^X
05 LN
06 CHS
07 WL0
08 LASTX
09 /
10 RTN
11 .END.

now I will make it 100% RPN according the links above just for my HP41CV
(that diva dont switch on with any clonix/nov module since yesterday; I suppose it dont like any climate change around the house.. but this is another story)
in order to work with standard functions (probably no need to post/update anything more here since the remarks and hints of all made all clear).

THANKS THANKS.

Update: full programm and documentation in TXT attachment
