Dyalog Version 10

Dyalog Windows Version 10 for Windows NT, ME, 2000 and XP was released in March 2003.

Summary

Version 10 includes all of the capabilities of Dyalog.Net but does not require the installation of the .NET Framework. Version 10 therefore replaces both Version 9 and Dyalog.Net. Dyalog for Windows product line is now reduced to a single version once again.

Version 10 includes several performance enhancing features.

	Idiom Recognition automatically replaces a set of primitive combinations (such as /?)  with highly optimised code, boosting performance of commonly used idioms.
	A super-fast matrix iota function is provided, based upon a specially optimised idiom for this operation.
	It is also now possible to obtain much faster lookup speed by saving the hash tables associated with  ?, 1 and other set primitives. This avoids the tables being recalculated when you perform repeated look-ups in the same array.
	A new system function ΠMAP allows you to associate APL arrays with mapped file. Access to the data in the files is about as fast as it gets under Windows.

The Grid object now supports multiple-selection and can host ActiveX Controls and .NET classes. The Grid also allows row and column headings to be displayed in different colours.

A new ColorButton Object is included. This provides a simple and consistent user-interface for selecting colours, and is also supported by the Grid.

The Version 10 Session provides several enhancements, including AutoCompletion, a popular feature of  Pocket APL.

Version 10 allows you to package a workspace as a .exe.
