Prism language definition for IBM UIM, 2017 version

Prism language definition for IBM’s UIM tag language, updated for 2017.

User Interface Manager (UIM) is a tag-based language much like HTML that can be programmed on IBM i / iSeries / AS/400 computers for menus, displays, and help text. All of the regular 5250-based menus, such as GO MAIN or WRKSPLF are UIM panels.

For 2017, as part of the site migration to Grav, I am looking at the custom code highlighting previously used to see if I can make improvements. The first effort is for UIM because it is a small tag-like language. The Prism language definition for markdown heavily influenced this new version. Instead of worrying about specific language tags such as :pnlgrp., the rules are more generic, such as “a tag begins with a colon and ends with a period” and “the first item after the colon is the tag name.”

For more information about UIM, see “Chapter 16. Introduction to the User Interface Manager” in this PDF. UIM is a “mature” specification so don’t let the V4R1 documentation throw you off.
