3. What is eagle? EAGLE is a set of CICS programs that provides a TCP-enabled application, development, control, and communications environment. EAGLE

4. What is eagle? IBM’s CICS * is the world’s most reliable, robust, and speedy customer information system. EAGLE

5. What is eagle? However, CICS is primarily a mainframe application and has inherited some communications interface issues: EAGLE

6. What is eagle? It was never designed to talk via any interface except SNA. EAGLE

7. What is eagle? It was never designed to talk via any interface except SNA. Data access was often tightly linked to display logic. EAGLE

8. What is eagle? In short, while CICS provides fast, robust access to data, this access has been restricted by a simplistic, antiquated interface. EAGLE

9. A little history To understand what EAGLE does, it would be helpful to understand the problems it was originally created to solve. EAGLE

10. A little history Once upon a time in the swamplands of North Florida… EAGLE

11. A little history Once upon a time in the swamplands of North Florida… EAGLE UF is the state's oldest, largest and most comprehensive university. With more than 46,500 students, UF is among the five largest universities in the nation.

12. A little history Once upon a time in the swamplands of North Florida… EAGLE In the middle 1990s, the popularity of the World Wide Web made the Web browser an ideal method for students to access their registration functions and information.

13. A little history Once upon a time in the swamplands of North Florida… EAGLE However, access methods had not kept pace with the exponential growth of the Internet. The only practical way to provide Web interaction with CICS data at this time was via “screen- scraping”.

14. A little history EAGLE SNA 3270 (“Dumb Terminal”) OS/390

15. A little history EAGLE TCP client (WWW, e.g) OS/390 AgentSoftware(Middleware) Webserver TCP NT or UNIX or OS/2 SNA TCP

16. A little history Once upon a time in the swamplands of North Florida… EAGLE At great expense, UF installed one of these “screen-scraping” systems to provide students with a Web interface to UF’s legacy CICS resources. It was… less than successful. However, the lessons learned in the process of implementation proved invaluable in developing EAGLE later on.

17. A little history Once upon a time in the swamplands of North Florida… EAGLE The first public iteration of EAGLE delivered student’s grades in the spring of 1998. Soon after that initial success, nearly all student registration functions were Web-enabled as EAGLE-powered applications.

33. A simple EAGLE page How do I create a page in EAGLE? EAGLE

34. A simple EAGLE page How do I create a page in EAGLE? The core object in EAGLE is the Page Definition. EAGLE

35. A simple EAGLE page How do I create a page in EAGLE? The Page Definition defines  the name of the page  where dynamic data (if any) lives  what programs (if any) are invoked EAGLE

36. A simple EAGLE page How do I create a page in EAGLE? When you create an Page Definition, you have created an EAGLE page… but there is nothing on it! EAGLE

37. A simple EAGLE page How do I create a page in EAGLE? Text is placed on an EAGLE page in one of two ways: EAGLE

38. A simple EAGLE page How do I create a page in EAGLE? Text is placed on an EAGLE page in one of two ways: Static data is placed on the Layout page… EAGLE

39. A simple EAGLE page How do I create a page in EAGLE? Text is placed on an EAGLE page in one of two ways: …dynamic data placement is specified with an anchor. EAGLE
