Line 1568 and

A variable of a module is declared with the key word @code{static}.

The static variables cannot be refered nor changed out of the module,

but it can be refered and changed in any functions in the module.

A global variable which can be refered and changed at any place

The @code{static} variables must be declared before the definitions of functions,

because the one-path parser of asir automatically assume variables as local variables

if there is no declaration for them.

A global variable which can be refered and changed in or out of the module

is declared with the key word @code{extern}.
