Use index searches to find appropriate topics:
LOGO Help is complete resource for a new (LOGO) user,or an expert. It contains command syntax's,practical advice,tutorials,and demonstrations to help you learn new things bout LOGO.The Table of Contents,like the TOC of this book,is used to find the topic of your interest .

It consist of three parts:                  
1.   Getting Started:This is the shortest section of LOGO help topics.It contains 'Why LOGO'and                     'Where to Start' sections.They  give a brief introduction of LOGO, and simple examples containing commands/primitives for beginners.
2. using the graphical user interface: this section consists of five subheadings, which help LOGO user to understand and get familiar with its GUL.
3.    using the language: this is the longest section in LOGO help topics. it contains details of how to use the LOGO language.

this section consists of advanced primitive and functions that help programmers write batter programs.
if, for any reason, you not able to locate your LOGO topics, an index search will help you find your desired information.
let's take an example.  you come across the following program:
make "zing [ ]
repeat 50 [make ''zing Iput recount* 10 :zing make ''zing Iput 100 :zing]
sound :zing
now, be the looks of the program, you know that it will make some kind of sound. you are familiar with LOGO primitives such as 'repeat' and 'sound'. but you have not come across primitives such as 'make',Iput' and 'recount'. this is where the LOGO index comes handy.

let's take the primitive 'recount' and see how a find its usage and syntax.
1.     open the 'help' menu.
2.       click on 'index'.
3.        enter 'recount' (via keyboard). as you types, the index  display area will keep on changing, until your desired topic is displayed.
