Though Perl is not officially an acronym, there are various backronyms in use, such as: Practical Extraction and Reporting Language. Perl was originally developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions. The latest major stable revision of Perl 5 is 5.18, released in May 2013. Perl 6, which began as a redesign of Perl 5 in 2000, eventually evolved into a separate language. Both languages continue to be developed independently by different development teams and liberally borrow ideas from one another. History Early versions Wall began work on Perl in 1987, while working as a programmer at Unisys, and released version 1.0 to the comp.sources.misc newsgroup on December 18, 1987. The language expanded rapidly over the next few years. Perl 2, released in 1988, featured a better regular expression engine. Early Perl 5 2000–present Name

Perl programming documentationC Sharp (programming language)C♯ is intended to be a simple, modern, general-purpose, object-oriented programming language. Its development team is led by Anders Hejlsberg. The most recent version is C♯ 5.0, which was released on August 15, 2012. The ECMA standard lists these design goals for C#: Due to technical limitations of display (standard fonts, browsers, etc.) and the fact that the sharp symbol (U+266F ♯ music sharp sign (HTML: ♯)) is not present on the standard keyboard, the number sign (U+0023 # number sign (HTML: #)) was chosen to represent the sharp symbol in the written name of the programming language. This convention is reflected in the ECMA-334 C# Language Specification. However, when it is practical to do so (for example, in advertising or in box art), Microsoft uses the intended musical symbol. C# used to have a mascot called Andy (named after Anders Hejlsberg). It was retired on Jan 29, 2004. C# has the following syntax:

Getting started with C# A simple C# program and where to get tools to compile it. Basics Basic syntax Describes the basics in how the applications you write will be interpreted. Naming conventions Quickly describes the generally accepted naming conventions for C#. Variables The entities used to store data of various shapes. Operators Summarizes the operators, such as the '+' in addition, available in C#. Data structures Enumerations, structs, and more. Control statements Loops, conditions, and more. Exceptions Responding to errors that can occur. Classes Namespaces Giving your code its own space to live in. Classes The blueprints of objects that describes how they should work. Objects Cornerstones of any object-oriented programming language, objects are the tools you use to perform work. Encapsulation and accessor levels Inheritance Generics
Damien Learns Programming: Launch your Perl script from Notepad++Today I am going to explain how you can be using Notepad++ to run Perl scripts. It can be convenient to launch your program directly from the editor's environment to quickly check that it compiles. Let's try and set up Notepad++ to launch the script from Wednesday's post. In the Plugins menu, you will find the NppExec plugin.Select Plugins>NppExec>Execute... You can also use the convenient F6 shortcut. Once the Execute... window is open, type in the following command:perl "$(FULL_CURRENT_PATH)"$(FULL_CURRENT_PATH) is an internal Notepad++ variable that contains the full path of the file currently open in the editor. You can save this command line and give it a meaningful name ('perl' for example). The output result is visible on the Console window. You can get rid of the "Process..." lines by selecting Plugins>NppExec>No Internal Message Also, if you want to repeat the previous command, you can just type Ctrl+F6. If you know more Notepad++ tips, I'd love to hear from you! Come on, try it!
