ASCII and EBCDIC Compared ASCII is quite elegant in the way it represents characters, and it is very easy to write code to manipulate upper/lowercase and check for valid data ranges. EBCDIC (Extended Binary Coded Decimal Interchange Code) is a character encoding set used by IBM mainframes.

How Coding Works So how does coding work, really? The short answer is that writing code tells the computer what to do, but it’s not quite that simple. So here’s the longer answer. A computer can only understand two distinct types of data: on and off. In fact, a computer is really just a collection of on/off switches (transistors). Anything that a computer can do is nothing more than a unique combination of some transistors turned on and some transistors turned off.

What does EGSstand for? The EGS computer code system is a general purpose package for the Monte Carlo simulation of the coupled transport of electrons and photons in an arbitrary geometry for particles with energies from a few keV up to several TeV. It was developed at SLAC. Some have referred to EGS as the de-facto gold standard for clinical radiation dosimetry.

Wavell Heights, Queensland From Wikipedia, the free encyclopedia. Wavell Heights is a Brisbane suburb located 9 kilometres (5.6 mi) north of the Brisbane central business district. It is named after Field Marshal Lord Wavell who was the Commander-In-Chief of the Allied Forces in the Middle East during the Second World War.8.5% of people living in Wavell Heights were born in Australia, compared to the national average of 69.8%; the next most common countries of birth were New Zealand 3.7%, England 3.2%, Philippines 0.8%, India 0.8%, Italy 0.6%.

G-code G-code (also RS-274), which has many variants, is the common name for the most widely used numerical control (NC) programming language. It is used mainly in computer-aided manufacturing to control automated machine tools. G-code is sometimes called G programming language, not to be confused with LabVIEW 's G programming language. G-code is a language in which people tell computerized machine tools how to make something. The how is defined by instructions on where to move, how fast to move, and what path to move.

Legacy systems continue to have a place in the enterprise Liverpool Victoria is one example of a company that has successfully integrated mainframe systems with a browser-based front end in this manner. The insurance company's car business suffered from a website that mapped directly on to mainframe data.

- Pseudocode is a description of a computer programming algorithm that uses the structural conventions of programming languages, but omits detailed subroutines or language-specific syntax. An example of how pseudocode differs from regular code is below. Regular code (written in PHP): <?php. if (is_valid($cc_number)) {. execute_transaction($cc_number, $order); } else {.

- On mainframe computers, channels are used to send data to and from peripheral devices. Channels are small computers that control the flow of data to and from peripheral devices. Buffers hold the data while the channels coordinate the sending of the data.

Introduction to Programmable Controllers In these modern times a PC with specially dedicated software from the PLC manufacturer is used to program a PLC. The most widely used form of programming is called ladder logic. Ladder logic uses symbols, instead of words, to emulate the real world relay logic control, which is a relic from the PLC's history.

Scheme (programming language) (Redirected from Scheme programming language) Scheme is a functional programming language and one of the two main dialects of the programming language Lisp. Unlike Common Lisp, the other main dialect, Scheme follows a minimalist design philosophy specifying a small standard core with powerful tools for language extension.

COBOL The DATA DIVISION of a COBOL (sub)program contains two sections, the FILE SECTION and the WORKING-STORGAGE SECTION. The latter is used to describe, via data description entries (level numbers, PICTURE clauses, etc.), the hierarchical structure of data items that exist during execution of the program.andom Access form of READ, WRITE, and REWRITE for INDEXED files. 1  Place desired value into the key field (in the file's data record). 2  Place desired contents into file's data record (or the data item specified in the FROM clause).

Character Encoding / Line Ends Why it matters-If you use a package like FTP to download a web-based Text (i.e. ASCII) file (where Unix is the assumed operating system) to an MS-DOS based system, the FTP process will automatically scan the file and replace each line feed character with a carriage return-line feed pair. byte is the collection of bits used by a particular computer for the most common character encoding scheme used by that computer. The most common byte size is 8 bits, but 6, 7, 9, and 12-bit bytes are used by some (different) computer systems.

- Mainframes are often thought of as being enormous computers, however the size is actually immaterial. The smallest mainframe consists of just a single cabinet housing the processors, memory, hard-drives and backup facilities, not much unlike a standard desktop computer (albeit slightly bigger).ainframe is much more powerful, it is the main computer of a computational center, it can be used in banks and large organizations.

CNC Programming: G-Code is the language used to control CNC machines. It's one type of CNC programming that CNC programmers use, the other type being CAM programming. Your machine's CNC controller probably executes g-code, although there are other possibilities--Heidenhain, Mazak, and others have proprietary formats. Some machines with proprietary formats can also run g-code.

- CAM Post Processors for G-Code Dialects: The Post Processor is the component of your CAM software that is responsible for translating to the exact g-code dialect. Use MDI for Quick and Easy CNC Work: Pretend your CNC is just a manual machine with DRO's and Power Feeds on every axis. Conversational CNC: G-Code from point and shoot Wizards. For quick and easy parts you don't need CAD or CAM for.

Core System Core System. Core System. The first proposed standard for computer graphics, developed by the Graphics Standards Planning Committee of SIGGRAPH and used in the late 1970s and early 1980s. Its objectives were portability of programs between computers and the separation of modeling graphics from viewing graphics.

Computer Programming - Basic Syntax For example, the above program makes use of two functions: main() and printf(). Here, the function main() provides the entry point for the program execution and the other function printf() is being used to print an information on the computer screen.

Introduction This suite of programs provides an example of how a COBOL program may be used to define a binary table and then display data strings that have embedded binary (or non-display and non-print) values by removing the binary characters. This is accomplished by replacing the binary characters with space characters.
