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

What is eagle?: What is eagle? IBM’s CICS* is the world’s most reliable, robust, and speedy customer information system. EAGLE
What is eagle?: What is eagle? However, CICS is primarily a mainframe application and has inherited some communications interface issues: EAGLE

Data access was often tightly linked to display logic. EAGLE
What is eagle?: What is eagle? In short, while CICS provides fast, robust access to data, this access has been restricted by a simplistic, antiquated interface. EAGLE

A little history: 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.

A little history: 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.
A little history: 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.

A simple EAGLE page: A simple EAGLE page How do I create a page in EAGLE? EAGLE
A simple EAGLE page: A simple EAGLE page How do I create a page in EAGLE? The core object in EAGLE is the Page Definition. EAGLE
A simple EAGLE page: 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 To make a page that uses the ESP engine, first create an ESP Layout object…
