Introduction aad Tutorial

The line you just typed may be deleted character-by-character with the <RUBOUT) key or in its.entirety with the key configured to <DELLI ), delete line (usually configured to (CTRL-Z». Delete the line. The file is now empty, and the EOF marker is back in the upper left-hand corner of the screen. The cursor, however, remains in the same position on tbe screen until the next command is given.

Now type the following sentence. Enter the text exactly as shown-several words are deliberately misspelled.

The first word in the sentence, levell, is misspelled. To correct this error, use the cursor control keys to position the cursor "over" the erroneous I. The cursor is moved by the cursor control keys (arrows), in the direction indicated by the arrow. (There- fore, press the up arrow ( < UP ) ) twice to move the cursor to the first line. Then press the left arrow <LEFT) followed by <HOME) -the <HOME) key is used in conjunction with the cursor control keys for fast cursor movement-to move the cursor to the first position in the line. Now press the right arrow <RIGHT) nine times to position the cursor ··on" the first I.) Then press the key configured to <DELCH ) , delete character (usually configured to <CTRL-F) ) to delete the extra I.

The s in Pascal has been omitted. To correct this error, position the cursor on the c in Pascal and type s. Text automatically moves to the right as the s is inserted.

Press <ESC) to leave INSERT mode and return to main command level.

The word model is misspelled modal. To correct the error, type X to enter XCHANGE mode.

The word [exchange] is displayed at the bottom of the screen, indicating that you are in XCHANGE mode. Position the cursor ··over" the a and type e.

Press <ESC) to leave XCHANGE mode and return to main command level.

You have learned how to insert text, exchange text, and delete individual characters. Now type the following sentence exactly as shown. First, type I. Then, position the cursor below the lines you just typed. Move the cursor to the end of the line using the right arrow key ( <RIGHT) ) followed by <HOME), then press <DOWN) twice and <RETURN) once. The cursor is now positioned at the end of the file and at the beginning of an empty line. Type the following lines exactly as shown:

-_S " . g" - :evf .la~guages are eas.er and faster to (RETURN)

. 'e :ha~ .=,,-:e~el ,a~gJajes 5.~ce Dre :es5 leS5 <RET"RN)

- " - 5 . at . : - 5~e~ 15 reql...red -ro'" co~ce;:t to code.(RETJRN)

Press <ESC) to leave INSERT mode and return to main command level.

Note that the word less is typed twice. To correct this error position the cursor on the I of the second less. Because it appears at the end of the line, it may be deleted with <DELR ) . Press the key configured to <DELR ) , delete right (usually confi- gured to <CTRL-A ) ). The <DELR) command deletes all text to the right of the cursor.

Suppose you wish to delete the phrase from concept to code from the text, leaving the period at the end of the sentence. To do this, you must ··block" (i.e., delimit) this section from the rest of the text using the BLOCK command followed by the Delete subcommand.

AEDIT-86 specifications

The Intel AEDIT-86, also known as the Intel 8086, is a notable microprocessor that played a critical role in shaping the computing landscape. Released in 1978, it was Intel's first 16-bit microprocessor, setting the stage for the x86 architecture that continues to influence modern computing.

One of the main features of the AEDIT-86 is its 16-bit architecture, which allows it to process data in larger chunks compared to its 8-bit predecessors. This capability not only improves performance but also increases the amount of memory that can be addressed, allowing for a maximum of 1 MB of RAM. This was a significant advancement at the time, enabling more complex software and operating systems to run efficiently.

The AEDIT-86 is built on a 3-micron process technology, which was innovative for its time and contributed to its performance capabilities. The microprocessor operates at a clock speed of up to 5 MHz, which allowed it to execute more instructions per second than previous generations of processors. This speed, combined with its wide data bus (16 bits), enables the processor to handle a larger volume of information more quickly.

Intel incorporated several key technologies in the AEDIT-86, including segmentation. This feature divides the memory into different segments, making it easier for programs to access data and improving memory management. The AEDIT-86 also supports a minimum of four 64 KB segments, which enhances the organization and access of programs and data in memory.

Another significant aspect of the AEDIT-86 is its compatibility with the existing 8080 and 8085 instruction sets, which facilitated easier migration for developers and helped the processor gain traction in the market. This backward compatibility allowed existing software to be ported to the new platform with minimal modification.

Furthermore, the Intel AEDIT-86 introduced a powerful instruction set that includes both integer and string manipulation commands, paving the way for more versatile programming. The instruction set architecture (ISA) of the AEDIT-86 supports both high-level programming languages and low-level assembly language, offering flexibility for various applications.

In summary, the Intel AEDIT-86 is a groundbreaking microprocessor known for its 16-bit architecture, advanced segmentation technology, and compatibility with earlier instruction sets. Its introduction marked the beginning of the x86 architecture, which has influenced countless processors and computing systems that followed. The AEDIT-86's features and technologies were instrumental in the evolution of personal computing, laying the groundwork for future innovations in the industry.
