APLScript is a Dyalog scripting language. Designed originally to support the specification of ASP.NET Web Pages and Web Services in APL, APLScript may also be used outside the Microsoft .NET environment. An APLScript is not workspace oriented (although you can call workspaces from it) but is simply a Unicode character file containing function bodies and expressions. APLScript files may be viewed and edited using any character-based editor such as Notepad or Microsoft Word. APLScript files are compiled by aplc.exe, the Dyalog APLScript compiler.

Please see APLScript Compiler further down.
In order to type Dyalog symbols into an APLScript file, a Dyalog Input Method Editor (IME) is included and automatically added to your working set of IMEs during installation.

There are basically three types of APLScript files that may be identified by three different file extensions.
• .aspx files specify .NET classes that represent ASP.NET Web Pages
• .asmx files specify .NET classes that represent ASP.NET Web Services
• .apl files may specify general .NET classes

Note that .apl files may also be used simply to represent an APL application in a script format as opposed to a workspace format. Such applications do not necessarily require the Microsoft .NET Framework.
