function scope javaclasspath

[JonG]

Hi,

I've just started learning Octave. I made a script file that says:

disp(javaclasspath);

when i run that it displays my javaclasspath as expected,

but if I put that in a function file qweqwe.m:

function qweqwe()
disp(javaclasspath);
endfunction

it displays:

{
   [1,1] =
}

- what's going on here ? Presumably it's to do with the scope of 
variables in functions. How would I correctly reference the 
javaclasspath in a function ?

cheers
