A-Flow - Version 3.10 A-Flow is a general-purpose software development and authoring tool suitable for creating a wide range of Windows applications. A-Flow completely visualizes applications under development. You do not write application code but rather draw it by using a point-and-click approach. A-Flow also provides interoperability with other software, even when developed by other means and running under other operating platforms in a distributed computing environment. A- Flow is itself a native 32-bit Windows application.
