Editing Commands

AEDIT-86 User's Guide

3.5.2 <DELCH )

The DELETE CHARACTER command is configurable, usually as <CTRL-F ) . It deletes the character uunder" the cursor. If a carriage return is deleted, the following line feed (if any) is also deleted because in this case, AEDIT-86 considers the carriage return/line feed pair as a single character.

There is no recovery from this deletion.

Count. This command limits count to 32 to prevent accidental destruction of the file. If count is greater than 32, the message "cannot delete more than 32" is displayed on the message line.

3.5.3 <DELL)

The DELETE LEFT command is configurable, usually as <CTRL-X ). It deletes all characters to the left of the cursor on the line on which the cursor is positioned.

The deletion can be recovered with the <UNDO) command.

Count. The DELETE LEFT command ignores count.

Related Commands. <UNDO)

3.5.4 <DELR )

The DELETE RIGHT command is configurable usually as <CTRL-A). It deletes all characters to the right of the cursor on the line on which the cursor is positioned, except for the carriage return/line feed pair.

The deletion can be recovered with the <UNDO) command.

Count. The DELETE RIGHT command ignores count.

Related Commands. <UNDO)

3.5.5 <DELLI)

The DELETE LINE command is configurable, usually as <CTRL-Z). It deletes the entire line on which the cursor is positioned. All lines below the deleted line move up one row. The cursor is left in the same position on the new line.

The deletion can be recovered with the <UNDO) command.

Count. The DELETE LINE command ignores count.

Related Commands. <UNDO)

3.6 <UNDO) Command

The UNDO command is configurable, usually as <CTRL-U ) . It restores charac- ters deleted by the last DELETE LEFT, DELETE RIGHT, or DELETE LINE command at the current cursor position. If the previous command was DELETE LINE, the cursor moves to the beginning of the current line before the restoration. Consecutive <CTRL-U ) s repeat the restoration of the same string.

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.
