snl语言是一个简单的具有嵌套过程定义的过程式语言

{并列过程声明测试程序}
{输入三个整数，如果小于10,则加上10；否则，减去10}
program  example
type w1=integer;
     w2=record
          integer  x;
          integer  y,z;
        end;
var  integer c; 
     integer b;
     w1 a;
     w2 d;
procedure sd(integer s1;var integer s2); 
begin
   if s1<10
   then s2:=s1+10
   else s2:=s1-10	
   fi
end
procedure sss(integer a);
begin
   write(a)
end
begin      
   read(a);
   sd(a,c);
   d.x:=c;
   b:=d.x;
   sss(b);
   read(a);
   sd(a,c);
   d.y:=c;
   b:=d.y;
   sss(b);
   read(a);
   sd(a,c);
   d.z:=c;
   b:=d.z;
   sss(b)
end.
