Version 9.3 of Icon

Version 9.3 of Icon is available for MS-DOS, and Microsoft Windows. The Windows implementation supports Icon's graphics facilities. For Unix systems (including Macintosh) see Version 9.4.

Version 9.3 supersedes Version 9.1 (there was no 9.2 release) and corresponds to the third edition of The Icon Programming Language.

The main changes from Version 9.1 relate to bug fixes and improvements in the handling of graphics. There are three changes to language features:

There is a new function, serial(X) that returns the serial number of X if it is a type that has one.
Color names are now insensitive to case.
The default for i in WDelay(W, i) is now 1.
