facility. The name is shorthand for "Unified Extended Dialect of Icon."
Compared with Icon, many of the new features of Unicon are extensions to the I/O and system interface, to complement Icon's core control and data structures. Rather than providing lower-level APIs as-is from C, Unicon implements higher level and easier to use facilities, enabling rapid development of graphic- and network-intensive applications in addition to Icon's core strengths in text and file processing.
Exception handling is a programming language construct or computer hardware mechanism designed to handle the occurrence of exceptions, special conditions that change the normal flow of program execution....

. It includes useful chapters on topics such as the use of Unicon for CGI. Recent additions to Unicon include XMLHttpRequest
XMLHttpRequest
XMLHttpRequest is an API available in web browser scripting languages such as JavaScript. It is used to send HTTP or HTTPS requests directly to a web server and load the server response data directly back into the script. The data might be received from the server as XML text or as plain text...
