[Octave-bug-tracker] [bug #46459] Interpreter allows number assignment to "end" key word within array brackets

[Rik]

Update of bug #46459 (project octave):

                  Status:                    None => Confirmed              
        Operating System:               GNU/Linux => Any

Follow-up Comment #1:

Confirmed.

'end' is a reserved keyword and it shouldn't be possible to assign to it. 
This is the case at the command line as shown below.  I also used another
keyword, 'for' to show that in this case the interpreter is consistent and
does not allow the assignment.


octave:3> x = [1 2 3];
octave:4> end = 3
parse error:

  syntax error

>>> end = 3
      ^

octave:4> for = 5
parse error:

  syntax error

>>> for = 5
        ^

octave:4> x(end=2)
ans =  2
octave:5> whos
Variables in the current scope:

   Attr Name        Size                     Bytes  Class
   ==== ====        ====                     =====  ===== 
        ans         1x1                          8  double
        end         1x1                          8  double
        x           1x3                         24  double

Total is 5 elements using 40 bytes

octave:6> x(for=2)
parse error:

  syntax error

>>> x(for=2)
