Ans:We can not trace out at which point the value of variable is changed.
What is Service Program?
Ans:A Service Program is a collection of runnable procedures and available data items easily accessible by other ILE programs. In many respects it is similar to a subroutine library and procedure library.
A service program differs from a program in two ways:
It does not contain a program entry procedure. This means that you cannot call a service program using the CALL operation.
A service program is bound into a program or other service programs using binding by reference.

How to use PageRank?
PageRank is one of the methods Google uses to determine a page?s relevance or importance. It is only one part of the story when it comes to the Google listing, but the other aspects are discussed elsewhere (and are ever changing) and PageRank is interesting enough to deserve a paper of its own.
PageRank is also displayed on the toolbar of your browser if you?ve installed the Google toolbar (http://toolbar.google.com/). But the Toolbar PageRank only goes from 0 ? 10 and seems to be something like a logarithmic scale:
We can?t know the exact details of the scale because, as we?ll see later, the maximum PR of all pages on the web changes every month when Google does its re-indexing! If we presume the scale is

Explore The Google Pagerank Algorithm and How It Works
Introduction to Google PageRank Algorithm
Page Rank is a topic much discussed by Search Engine Optimization (SEO) experts. At the heart of PageRank is a mathematical formula that seems scary to look at but is actually fairly simple to understand.
Despite this many people seem to get it wrong! In particular ?Chris Ridings of www.searchenginesystems.net? has written a paper entitled ?PageRank Explained: Everything you?ve always wanted to know about PageRank?, pointed to by many people, that contains a fundamental mistake early on in the explanation! Unfortunately this means some of the recommendations in the paper are not quite accurate.
By showing code to correctly calculate real PageRank I hope to achieve several things in this response:
- Clearly explain how PageRank is calculated.
- Go through every example in Chris? paper, and add some more of my own, showing the correct PageRank for each diagram. By showing the code used to calculate each diagram I?ve opened myself up to peer review - mostly in an effort to make sure the examples are correct, but also because the code can help explain the PageRank calculations.
- Describe some principles and observations on website design based on these correctly calculated examples.
Any good web designer should take the time to fully understand how PageRank really works - if you don?t then your site?s layout could be seriously hurting your Google listings

How Search Engines Operates
Search engines have a short list of critical operations that allows them to provide relevant web results when searchers use their system to find information.
- Definition: Crawling the Web
Search engines run automated programs, called "bots" or "spiders", that use the hyperlink structure of the web to "crawl" the pages and documents that make up the World Wide Web. Estimates are that of the approximately 20 billion existing pages, search engines have crawled between 8 and 10 billion. - Definition: Indexing Documents
Once a page has been crawled, its contents can be "indexed" - stored in a giant database of documents that makes up a search engine's "index". This index needs to be tightly managed so that requests which must search and sort billions of documents can be completed in fractions of a second.

Characteristics of an Ideal Defensible Traffic Source
Let?s start first with a general idea of the type of defensible traffic you should be building. While the following points are ideal conceptualizations, they may help you to assess the value of your referral traffic sources.
The traffic source you are developing should:
- Promote your brand.
- Reinforce or build the existing community around your site

- Sustain itself over time, without requiring consistent active effort.
- Complement your overall site monetization strategy
how to grow a Web Site's Popularity
While developing a great website is half of the SEO equation, the other half is promotion. Search engines are very particular about growing their ability to detect artificial manipulation and link spam, so effective SEOs who want to promote sites to the fullest extent must use natural, organic link building processes in order to have success.
The techniques and approaches described below are all ultimately designed to improve search engine rankings by growing the number and quality of links that point to a website.
However, each also offers natural growth of your user base and provides visitors that come through systems other than search engines. Strangely, although the goal of SEO is better search rankings, the best sites in each industry often receive 50% or fewer of their total visitors from search engines. Why? Because if thousands of visitors are anxiously visiting your site via bookmarks, links, and direct type-ins at the address bar, you've achieved the content and status necessary to not only be ranked exceptionally well, but have visitors that know your site and want to visit, no matter what the search engines say. This methodology is particularly valuable because a site that doesn't rely entirely on search engines for traffic, ironically, has a far better chance of getting visitors through them.

Learn how to Build a Traffic-Worthy Site
One of the most important (and often overlooked) subjects in SEO is building a site deserving of top rankings at the search engines. A site that ranks #1 for a set of terms in a competitive industry or market segment must be able to justify its value or risk losing out to competitors who offer more. Search engines' goals are to rank the best, most usable, functional, and informative sites first. By intertwining your site's content and performance with these goals, you can help to ensure its long-term prospects in the search engine rankings.
Usability
Usability represents the ease-of-use inherent in your site's design, navigation, architecture, and functionality. The idea behind the practice is to make your site intuitive so that visitors will have the best possible experience on the site. A whole host of features figure into usability, including:- Design
The graphical elements and layout of website have a strong influence on how easily usable the site is. Standards like blue, underlined links, top and side menu bars, logos in the top, left-hand corner may seem like rules that can be bent, but adherence to these elements (with which web users are already familiar) will help to make a site usable. Design also encompasses important topics like visibility & contrast, affecting how easy it is for users to interest the text and image elements of the site. Separation of unique sections like navigation, advertising, content, search bars, etc. is also critical, as users follow design cues to help them understand a page's content. A final consideration would also take into account the importance of ensuring that critical elements in a site's design (like menus, logos, colors, and layout) were used consistently throughout the site.
Learn about Critical Components of Optimizing a Web Site
Each of the following components are critical pieces to a site's ability to be crawled, indexed, and ranked by search engine spiders. When properly used in the construction of a website, these features give a site/page the best chance of ranking well for targeted keywords.
The biggest problems in accessibility that most sites encounter fit into the following categories. Addressing these issues satisfactorily will avoid problems getting search engines and visitors to and through your site.
Accessibility
An accessible site is one that ensures delivery of its content successfully as often as possible. The functionality of pages, validity of HTML elements, uptime of the site's server, and working status of site coding and components all figure into site accessibility. If these features are ignored or faulty, both search engines and users will select other sites to visit.The biggest problems in accessibility that most sites encounter fit into the following categories. Addressing these issues satisfactorily will avoid problems getting search engines and visitors to and through your site.
What is SEO?
SEO is the active practice of optimizing a web site by improving internal and external aspects in order to increase the traffic the site receives from search engines. Firms that practice SEO can vary; some have a highly specialized focus, while others take a more broad and general approach. Optimizing a web site for search engines can require looking at so many unique elements that many practitioners of SEO (SEOs) consider themselves to be in the broad field of website optimization (since so many of those elements intertwine).
This guide is designed to describe all areas of SEO - from discovery of the terms and phrases that will generate traffic, to making a site search engine friendly, to building the links and marketing the unique value of the site/organization's offerings.
