Editing Commands

Count. The <UNDO) command ignores count.

Related Commands. <DELL), <DELR ), <DELLI)

3.7 <HEX) Function Key

The <HEX) prefix (usual1y configured to <CTRL-H » is used to insert a character into the text as its ASCII value. This feature is useful in the following cases:

When the character to be inserted has no key; e.g., a character with a hexadeci- mal value over 7FH.

When the character to be inserted has a special function in the current mode, e.g., if you want to insert the <ESC) character into your text.

To insert a character using <HEX) , you should type <HEX), then two digits that are interpreted as the ASCII value of the character. <HEX) is unseen and not inserted; however, it directs the treatment of the next two characters. For example, if, in INSERT mode, you type < HEX) SA, the letter Z will be inserted at the cursor position.

<HEX) can be activated under INSERT, XCHANGE, and line-edited prompts. It cannot be activated at main command level.

3.8 INSERT Mode

INSERT mode allows you to enter text. To enter INSERT, press I. To exit INSERT mode and return to main command level, press <ESC) .

3.8.1 Description

Press I; AEDIT-86 prompts-

[insert]

The prompt [insert] is displayed whenever AEDIT-86 is in INSERT mode. Move the cursor to any location in the text and begin typing; the characters are inserted into the text.

<ESC) causes the editor to leave INSERT mode and return to main command level.

The cursor movement commands ( <LEFT), <RIGHT), <UP), <DOWN) , or < HOME) ), the delete keys ( < RUBOUT), < DELCH ), < DELLI) ,

<DELL), <DELR ) ), and <UN DO) al1 function the same as they do at main command level.

The cursor movement commands and the delete keys restart INSERT mode at the new location.

<RETURN) inserts a carriage return/line feed pair and moves the cursor to the beginning of the next line.

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.
