Using the HTTPCLIENT

Abstract MCP systems have since the late 1990s supported a web server. This allows external clients to submit HTTP requests to MCP applications and receive HTTP replies. But what about reversing the situation? Can MCP applications act as clients to an external web server?

Since MCP 13.0, the answer has been yes. The HTTPCLIENT component of CCF makes it relatively easy for applications written in COBOL and Algol to construct HTTP requests, send them to a remote web server or web service, receive an HTTP response, and parse that response to understand its content.

This presentation describes how to use the HTTPCLIENT and presents a few live examples of it in action. Interfacing with a web service often involves sending and receiving data in XML format, thus this presentation also serves as a companion to the presentation on Using the XMLPARSER.

Using the XMLPARSER

Abstract One of the most common data interchange formats has become Extensible Markup Language, or XML. Use of XML is particularly common in communications with a web service. To support this format, MCP systems since release 13.0 have provided the XMLPARSER, an API that can be used by MCP COBOL and Algol applications to construct and parse XML documents.

This presentation describes how to implement the XMLPARSER in MCP applications and discusses examples of its use. Because of the importance of XML in web service applications, this presentation integrates with the Using the HTTPCLIENT presentation that discusses how MCP applications can communicate with a web service.

I Didn't Know You Could Do That! (2015 Edition)

Abstract Back by popular demand! Like all mature computer systems, MCP systems have a lot of features and capabilities. Some of these are not obvious, or at least not very well known. Everyone has their favorite set of Tips & Tricks to make better use of the system, but no one knows all of them.

This presentation has a number of short offerings by multiple speakers, each describing a simple Tip or Trick you can take back to your shop and put to immediate use. There will be a brief write-up available on each one, and ample time for questions from the audience. At the end, a vote will be held to select Best Trick. The audience is also invited to bring their own favorite Tip or Trick and offer it in the time remaining. Come have some fun and learn something new.
