VAR Variables

[Carl Sebeny]

Why does the following macro code display the result
of 10 instead of 20?

var x;
x=10;
f();
print (x);
exit("Terminating normally...");
function f(){
    x = 20;
}

Hi Carl,

as I understand it, global variables should be declared with
"var" OUTSIDE any macro.

so, you can have:

var x;
macro 'test' {
   x=10;
   f();
   print (x);
   exit("Terminating normally...");
}
function f(){
     x = 20;
}
