AEDIT-86 User's Guide

The Tag subcommand is executed by pressing A, B, C, or D. The cursor jumps to the specified tag, previously set with the TAG command.

Error. Uno such tag" is displayed if the specified tag does not exist.

Related Command. TAG

Start

The Start subcommand is executed by pressing S. It moves the cursor to the start of the file.

End

The End subcommand is executed by pressing E. It moves the cursor to the end of the file.

Line

The Line subcommand is executed by pressing L. It prompts for a decimal value:

11n e :

The cursor jumps to the start of the designated line. (The first line of a file is number I; the maximum value allowed is 65536.) If the value entered is greater than the number of lines in the file, the cursor jumps to the EOF marker.

Error. "illegal value" is displayed if a value larger than the maximum value or any other illegal value is entered.

Position

The Position subcommand is executed by pressing P. It prompts for a decimal value:

column:

The cursor jumps to the designated position in the current line. The first position in a line is 0; the maximum value allowed is 254.

If the current line is shorter than the designated position value, the cursor jumps to the last position in the line.

If there is no character at the specified position (due to tab expansion), the cursor jumps to the next character.

Error. "illegal value" is displayed if a value larger than the maximum value or any other illegal value is entered.

3. 16 BLOCK Command

The BLOCK command is invoked by pressing B (or D; typing either B or D initially is equivalent). The BLOCK command allows you to delimit a section of text that can then be deleted, moved, or copied. The subcommand determines if the text will be

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.
