Caché interjob communication

Caché ObjectScript interjob communication demo.

Description

Interjob communication is a way by which two Caché processes can pass data to each other. The class IJC demonstrates its use by opening a second terminal while a process is running in the first.

The IJC class has the following methods:

• OpenTerminal() opens a terminal and returns its device ID. It has optional arguments for window position and size.
• CloseTerminal() closes a device.
• Demo() shows hows the two terminal methods work together.

Installation

Clone the class into your Atelier project through GitHub, or download the file and import it. Open a terminal in the project's namespace and run

Do ##class(User.IJC).Demo()

This class has been shown to work on Caché versions 2016.2 and later, but it should run on many older versions as well.
