Lessons Learned when Converting from APL+Win to Dyalog APL

Presenter: Alex Holtzappleu, METSIM
Date and Time: Mon 29 Sept, 1:30 PM (45 mins)

METSIM® is the leading chemical and mineral processing plant simulation software used by engineers and operators around the globe. Since 1982, all development has taken place using APL+Win, which served their products and our customers well. However, the environment in which all industries are operating has evolved, and improvements became necessary; Dyalog was selected as the replacement system to provide the tools and expertise in-house to ensure that METSIM continues to meet customer demands.

For the last 18 months, teams from MSI and Dyalog Ltd have worked together and successfully converted the METSIM source code to the Dyalog platform without losing any key features. Alex describes the conversion process, examining issues such as moving from Microsoft Windows specific APIs and UI to cross-platform tools that will also support Linux, without rewriting the application. He also discusses the planned source-code improvements, and the external APIs that will expand MSI’s product offerings.
