Hi,

This example from the ChangLog file does not work

octave-2.1.8:1>       function f (...)
>         for i = 1:nargin
          stdout << "argn(" << i << ") = `" << deblank (argn(i,:)) \
                 << "' and its value is " << va_arg () << "\n";
        endfor
      endfunction
      f (1+2, "foo", sin (pi/2))
>           stdout << "argn(" << i << ") = `" << deblank (argn(i,:)) \
>                  << "' and its value is " << va_arg () << "\n";
>         endfor
>       endfunction
octave-2.1.8:2>       f (1+2, "foo", sin (pi/2))
argn(1) = `error: `argn' undefined near line 3 column 57
error: evaluating index expression near line 3, column 57
error: evaluating argument list element number 1
error: evaluating index expression near line 3, column 48
error: evaluating binary operator `<<' near line 3, column 45
error: evaluating binary operator `<<' near line 4, column 18
error: evaluating binary operator `<<' near line 4, column 43
error: evaluating binary operator `<<' near line 4, column 56
error: evaluating for command near line 2, column 9
error: called from `f'


Also, I don't know how to use the new `for i=string',

octave-2.1.8:2> a="a b c d"
a = a b c d
octave-2.1.8:3> for i=a;i,end
error: invalid type in for loop expression near line 3, column 1
octave-2.1.8:3> for i="a b c";i,end
error: invalid type in for loop expression near line 3, column 1

This already worked in 2.1.7, but I thing that it is not what is meant:

octave-2.1.8:9> for m ="a":"d";m,end
m = 97
m = 98
m = 99
m = 100

Sometimes issuing `hold on' gives a parse error, while `hold "on"' does
not, e.g, if my ~/.octaverc has

   LOADPATH=["~/octave//::" DEFAULT_LOADPATH]

then after starting octave-2.1.8,

LOADPATH =
~/octave//::.:/usr/local/libexec/octave/site/oct/i386-pc-sco3.2v5.0.4//:/usr/local/share/octave/site/m//:/usr/local/libexec/octave/2.1.8/oct/i386-pc-sco3.2v5.0.4//:/usr/local/share/octave/2.1.8/m//
octave-2.1.8:1> help help
parse error:

>>> help help
            ^

octave-2.1.8:1> help "help"
help is a builtin text-function

help [-i] [topic ...]


I used to set my LOADPATH in .octaverc as:

    LOADPATH=["~/octave//:" LOADPATH]

now I am using

    LOADPATH="/u/jcard/octave//::"

Is this correct? I have tried several combinations nad this one *seems*
to work.


Thanks,
Joao
