In the third week of Dyalog ’19 recordings, Stig Nielsen from SimCorp A/S talks about recent work to turn a very large body of APL code, originally designed to work well on workstations, into a 3-tier solution. This requires turning everything “inside out”, making the application a service that can be called from cloud-based components. Fortunately, the parts of the application that have been implemented in APL have been using a model-driven approach to user interface specification for decades. This makes the task a lot simpler compared to some of the code written in other languages (which needs a complete rewrite). Stig explains both the obvious solution and the one that might actually work.

See you next week for the next three recordings from Dyalog ’19.
