During this period continued to develop computer software, programming language was no exception. At the start of the era of low level programming languages, then developed a high level programming language. It is characterized by the appearance of a method of programming offered by a programming language, that is, object-oriented programming (OOP). IDE (Integrated Development Environment) is a computer program that has some facilities that are required in the development of the software. The purpose of the IDEA is to provide all the necessary utilities in building software. As for the type of software text editor that can be used to manipulate the source code hereinafter referred to as the source code of programming languages such as Ultraedit, JediEdit, ClearEdit, cEdit, the Golden Pen, and so on. PuniEdit software is a text-based editor software that can simplify the user through correction, insertion, and modification of the source code. PuniEdit software is built using Borland Delphi 7.0 and SynEdit component. This software can be used for the Pascal programming language, C++ and HTML. In addition, the software PuniEdit can perform management of the token. This PuniEdit software, the user can clearly see every occurrence of the type of token as keywords (reserved word), identifier, operator, and so on.Keywords: Source code, programming language, source code is scanned.
