Since we are utilizing the C preprocessor, it cannot properly preprocess expressions

with @code{$}.

For example, even if @code{LIST} is defined, @code{LIST} in the expression

@code{LIST$} is not replaced. Add a blank before @code{$}, i.e.,

write as @code{LIST $} to make the proprocessor replace it properly.

\BEG

Optinal arguments may be given as a list

with the key word @code{option_list}

@code{option_list=[["key1",value1],["key2",value2],...]}.

It is equivalent to pass the optional arguments as

@code{key1=value1,key2=value2,...}.

@example

[101] dp_gr_main([x^2+y^2-1,x*y-1]|option_list=[["v",[x,y]],["order",[[x,5,y,1]]]]);

\BEG

Since @code{getopt()} returns an option list,

the optional argument @code{option_list=...} is useful when

we call functions with optional arguments from

a function with optional arguments to pass

the all optional parameters.

@example

% cat foo.rr

def foo(F)

OPTS=getopt();

return factor(F|option_list=OPTS);

@end example

@example

[3] load("foo.rr")$

[4] foo(x^5-1|mod=11);

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}.
