Editing Commands

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

The cursor movement commands <LEFT). <RIGHT). <UP). <DOWN) ,

<HOME), and the delete keys (except for <RUBOUT» <DELCH ) . <DELL), <DELR) and <DELLI) ,and <UNDO) work as at main command

level.

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

<R UBOUT) replaces the character to the left of the cursor with the original character (if it has been exchanged), with the following exceptions:

•If the line has been extended, < RUBOUT) works as at main command level and deletes the character immediately to the left of the cursor.

•If the cursor is at the original replacement location, <RUBOUT) moves one character to the left but does not delete the character.

<RETURN) replaces the character "under" the current cursor position with a carriage return/line feed pair and moves the cursor to the beginning of the next line.

<CTRL-C) restores original text (text before it was exchanged). However, once you have exchanged text and pressed <ESC) or restarted XCHANGE with any of the cursor movement commands « LEFT), <RIGHT), <UP), <DOWN), or <HOME) ), changes cannot be revoked by pressing <CTRL-C). After resto- ration, <CTRL-C) returns the editor to the main command level.

The <HEX). (MEXEC), <FETN). 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 Chapter 5.

( FETN) is the fetch numeric key. This character is unseen and not inserted. When

<FETN) is pressed, the next character (which is 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 is 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.

Macro execution in XCHANGE mode usually restarts the XCHANGE process. The only exceptions are non-modeless macros that contain non-restarting commands only. (See Section 5.3, "Macro Modes," for a description of modeless and non-modeless macros.)

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

Error. "Xchange limit is )00" is displayed if you attempt to exchange over )00 characters without restarting XCHANGE mode. XCHANGE mode has a limit of

100characters.

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.
