sysRPL - Last Element of a Composite

[FLISZT]

Hello,

In sysRPL, ^LASTCOMP (2BC006) is said to return the last element of a composite.
For that purpose, this command executes DUPLENCOMP (3627A) then NTHCOMPDROP (35BC3).

Indeed, if I do (i.e.):

Code:

{ 1 2 3 5 7 } 
#3627Ah SYSEVAL          @  DUPLENCOMP
#35BC3h SYSEVAL          @  NTHCOMPDROP

I get 7 which is the expected result.

However, when I do:

Code:

{ 1 2 3 5 7 }
#2BC006h SYSEVAL         @  ^LASTCOMP

the calculator (HP 50G) freezes. (Fortunately, ON + C works without data loss! )

Is an argument missing? What am I doing wrong?

Thank you for any hint.
