Global variables with Octave

Hi,

I have a problem with variables in functions:

This works :

function y = toto (x)
a = 5;
b = 20;
y = a*x+b;
endfunction

for x = 0:1:20
printf("Result = %fŠÜn",toto(x));
endfor

This does not work :

global a = 5;
global b = 20;
function y = toto (x)
y = a*x+b;
endfunction

for x = 0:1:20
printf("Result = %fŠÜn",toto(x));
endfor

error: `a' undefined near line 2 column 5
error: evaluating expression near line 2, column 5
error: evaluating binary operator `*' near line 2, column 6
error: evaluating binary operator `+' near line 2, column 8
error: evaluating assignment expression near line 2, column 3
error: called from `toto'
error: evaluating argument list element number 2

Is anyone able to help me.

Regards.

Eric Bouyoux.
