The remaining 9 bits represent an integer offset from the address of the next instruction.
Programming Languages: Principles and Paradigms
The bits in this line of code, in turn, represent the number to be copied into the register. We said earlier that execution stops when a halt instruction is reached. In our program example, that instruction is the fifth line of code, The halt instruction prevents the machine from continuing to execute the lines of code below it, which represent data values rather than instructions for the program.
As you might expect, machine language programming is not for the meek. Despite the improvement on the earlier method of reconfiguring the hardware, programmers were still faced with the tedious and error-prone tasks of manually translating their designs for solutions to binary machine code and loading this code into computer memory.
After translation, another program, called a loader, automatically loads the machine code for this instruction into computer memory. Programmers also used a pair of new input devices—a keypunch machine to type their assembly language codes and a card reader to read the resulting punched cards into memory for the assembler.
These new hardware and software tools made it much easier for programmers to develop and modify their programs. For example, to insert a new line of code between two existing lines of code, the programmer now could put a new card into the keypunch, enter the code, and insert the card into the stack of cards at the appropriate position.
The assembler and loader would then update all of the address references in the program, a task that machine language programmers once had to perform manually.
Moreover, the assembler was able to catch some errors, such as incorrect instruction formats and incorrect address calculations, which could not be discovered until run time in the pre-assembler era. Figure 1.
It is now possible for a human being to read what the program does. The program is also commented the text following each semicolon to clarify what it does for the human reader.

The assembly language code in Figure 1. An abstraction is a notation or way of expressing ideas that makes them concise, simple, and easy for the human mind to grasp. Civilization advances by extending the number of important operations which we can perform without thinking about them. A second major shortcoming of assembly language is due to the fact that each particular type of computer hardware architecture has its own machine language instruction set, and thus requires its own dialect of assembly language.
Therefore, any assembly language program has to be rewritten to port it to different types of machines. The first assembly languages appeared in the s. They are still used today, whenever very lowlevel system tools must be written, or whenever code segments must be optimized by hand for efficiency.
You will likely have exposure to assembly language programming if you take a course in computer organization, where the concepts and principles of machine architecture are explored. It reflected the architecture of a particular type of machine and lacked the structured control statements and data structures of later high-level languages.
The language has undergone numerous revisions in the last few decades, and now supports many of the features that are associated with other languages descending from its original version. Moreover, they wished to write these high-level instructions for different machine architectures with no changes. ALGOL provided first of all a standard notation for computer scientists to publish algorithms in journals.
As such, the language included notations for structured control statements for sequencing begin-end blocks , loops the for loop , and selection the if and if-else statements. These types of statements have appeared in more or less the same form in every high-level language since.
Likewise, elegant notations for expressing data of different numeric types integer and float as well as the array data structure were available. Finally, support for procedures, including recursive procedures, was provided. These structured abstractions, and more, are explored in detail later in this chapter and in later chapters of this book. ALGOL was one of the first programming languages to receive a formal specification or definition.
Its published report included a grammar that defined its features, both for the programmer who used it and for the compiler writer who translated it.

Programming Language Pragmatics. Data types are studied in Chapter 8 and declarations in Chapter 7. In this text, we study modules and abstract data types in Chapter 11, whereas classes and their relation to abstract data types are studied in Chapter 5.
Programming Languages: Principles and Paradigms
ALGOL provided first of all a standard notation for computer scientists to publish algorithms in journals. For example, the first instruction, , contains an opcode and codes for two operands.
A multicore architecture divides the central processing unit CPU into two or more general-purpose processors, each with its own specialized memory, as well as memory that is shared among them.
For example, to insert a new line of code between two existing lines of code, the programmer now could put a new card into the keypunch, enter the code, and insert the card into the stack of cards at the appropriate position.
