snl语言是一个简单的具有嵌套过程定义的过程式语言

program  example
type w1=integer;
     w2=record
          integer  x;
          char     y,z,m;
        end;
     w3=array [3..6] of integer;  {haha}

var integer p;
     w3 c;
     w2 d;
    integer a;

procedure sd(integer s1;var integer s2); 
var integer  x,y;
procedure sd1(integer y);
begin
   write(y)
end
begin
   if a=2
   then x:=s1*(5+7)+10
   else 
	x:=s1/9;
	sd1(x)
  fi;
   return
end

begin      
   while a<5
   do 
   sd(2,a);
   c[3]:=a*2;
   c[a]:=d.x;
   read(p)      
   endwh    
  
end.
