Global variable Vs normal variable?

1

Hi everyone:

I have question:

~freq 500 vs
var freq=500

What are the difference in programming meaning between global and normal variables?

I understands the programming of var freq=500, but ~freq not. Or ~ whatever.

could help, as might the entire document.

So:

1 question: ~Freq SinOsc.ar(500, 0. 0.5);

2 question: var freq=SinOsc.ar(500, 0. 0.5);

Difference in programming meaning and computational function?

Thanks, Peter.
Now! I understands, the difference.
