Software modernisation or re-engineering as a concept lacks universal clarity. System Building with APL + Win seeks to clarify this problem by identifying the solution to the long term survival of the APL application as the elimination of APL specific considerations in the choice of a development tool. The author shows how to deploy mainstream industry standard system components within an APL + Win development environment, enabling the APL application to be just like any application on the Windows platform. Demonstrates the power and agility of APL + Win in today’s approach to system buildingFeatures a ‘code intensive’ approach, which overcomes the lack of APL+Win specific documentation of system componentsIllustrates the potential for multi-language system building from an APL+Win environmentExplains how increasing the collaborative nature of APL will enable it to become an even more valuable tool for application development System Building with APL + Win provides an excellent resource for system developers and training providers using the software, as well as MS Office users who wish to incorporate it into a bespoke application development. It will also be of interest to users of other APL interpreters. RSP Series in Industrial Control, Computers and Communications
