Hi Bill,

I meant the term in this sense...

An integer variable:
int a

An integer constant:
5

Setting the variable to the constant:
a = 5

A pointer variable:
int *b

A pointer constant:
int c[10]

Setting the variable to the constant:
b = c

What I state above means that using c is faster/smaller than using b like
this:
*c = 2
*b = 2

Regards,
Oliver
