AEDIT-86 User's Guide

<CTRL-C) deletes all text inserted since the beginning of INSERT mode, or since INSERT mode was restarted by one of the following commands: cursor movement commands « LEFT), < RIGHT), <UP ), < DOWN) ) or delete keys ( <DELCH ), <DELLI), <DELL), <DELR ) ), but does not restore charac- ters deleted with <RUBOUT), < DELCH ), <DELLI), < DELL), or <DELR ). After restoration, <CTRL-C) returns the editor to main command level.

The <HEX), <MEXEC), <FET.N ), and <FETS) functions described here are the same in both INSERT and XCHANGE modes.

<HEX) is unseen and not inserted. The next two characters, which must be hexadecimal digits, are interpreted as the hexadecimal values of a character. < HEX) is described above.

<MEXEC) is the macro execution key. This character is unseen and not inserted. When < MEXEC) is pressed, the next character is treated as a macro name. <MEXEC) is described in detail in Chapter 5.

<FETN) is the fetch numeric key. This character is unseen and not inserted. When <FETN) is pressed, the next character (which must be a numeric value from 0-9)fetches the assigned value. <FETN) is described in Chapter 6.

<FETS) is the fetch string key. This character is unseen and not inserted. When

<FETS) is pressed the next character (which must be a numeric value from 0-9

or the second letter from the read-only string variables) fetches the assigned value. <FETS) is described in Chapter 6.

In INSERT mode, macro execution usually restarts the insert process. The only exceptions are non-modeless macros that consist of nonrestarting commands only. (See Section 5.3, "Macro Modes," for a description of modeless and non-modeless macros.)

INSERT mode is modified if it is preceded by a forward slash (0. All text past the cursor in the current line is moved down one line. The text is restored before any delete or move subcommand (except <RUBOUT) ) or when insertion is complete.

Count. Repeat count is not a valid option in INSERT mode.

3.9XCHANGE Mode

XCHANGE mode allows you to type over text. To enter XCHANGE, press X. To exit XCHANGE mode and return to main command level, press <ESC).

3.9.1Description

Press X; AEDIT-86 prompts-

(exchange)

The prompt [exchange] is displayed whenever AEDIT-86 is in XCHANGE mode. Move the cursor to any location in the text and begin typing; characters are replaced on a one-for-one basis. The carriage return/line feed pair is not replaced; instead, the line is extended.

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.
