Thanks.  I registered a new issue.

I ran into another case and would like you to comment.  "pause"  seems to be problematic.  Editor I have is notepad++. 

Please cut/paste these below into command window.  These two groups are the same except, for the latter, a carriage return is entered right after the pause. 

When I pasted the lines, the first pause does not work at all. 0 and 1 were displayed automatically without any feedback from me. After all done, I then used arrow up key back to the first line, pause works under this condition.

For the 2nd pause, at the end of the line, below, the first character of the line is always ignored/missing. 

display(0); pause, display(1)
display(0); pause,
display(1)

>>
>> display(0); pause, display(1)

0
1

>> isplay(0); pause,

error: 'isplay' undefined near line 1, column 1

>> display(1)

I pushed it here since it passed the tests I tried with it: https://hg.savannah.gnu.org/hgweb/octave/rev/bdbc67b5f92e

See if it works as intended for you when you get the overnight build.

Marking as ready for test.

I've got it. With the attached patch, this is the behavior:

Code to paste:

for i = 1:5
i
#{
  foo
  #{
    bar
  #}
  baz
#}
-i
end

Output:

octave:1> for i = 1:5
> i
> #{
>   foo
>   #{
>     bar
>   #}
>   baz
> #}
> -i
> end
i = 1
ans = -1
i = 2
ans = -2
i = 3
ans = -3
i = 4
ans = -4
i = 5
ans = -5

Please test this out. If it works as intended for you, I'll push it with bug number etc.

I agreed that it worked in 5.2.  Thanks.

Octave used to accept multiple line comments in command window as matlab always does.   The example below shows the error when the multiple line comments are grouped with other statement/command.  Thanks. 


for ii=1:1
%{       
%}
end

>> for ii=1:1

%{
%}

>> end

error: parse error:
