About the Book

Chapters: Posxml. Source: Wikipedia. Pages: 46. Not illustrated. Free updates online. Purchase includes a free trial membership in the publisher's book club where you can select from more than a million books without charge. Excerpt: POSXML (acronym for Point Of Sale eXtended Markup Language) is a programming language that is used to create applications for a POS terminal. Normally the programming language used to develop such applications is C or C++. This development requires an in-dept knowledge of both the technical specifications of the machine (Hardware) and the programming language. The main purpose of POSXML is to simplify the development of applications for POS terminals. It contains a set of instructions and pre-programmed commands, which allow direct interaction with the machine, resulting in a large reduction in application development time. Most of these instructions and commands are in Portuguese to simplify the understanding during the work on the applications, but it is perfectly possible to develop applications using an English syntax. The POSXML language, like the name suggests, follows the open standard language for XML, which is widespread in the software industry. The XML standard is fully flexible and allows a rapid expansion of language. Example: Every program written in POSXML contains a page called Main, which is the (main) application that will be stored in a POS terminal. The language allows you to write as many pages as necessary, or even write the whole application logic inside one page, the main page. The only restriction is that the size of the compiled page can't be larger than 32 Kbytes. To give an idea of the compression offered by the platform: a common application with 1600 lines of code contained 76 kbytes in POSXML, when compiled its size is reduced to 15 kbytes. Applications that have multiple pages are used (being deployed on a server, called WALK) with the softwareserver (gateway) c...More: http: //booksllc.net/?id=2520272
