Editing Commands

AEDIT-86 User's Guide

Pressing 0 a second time returns the editor to the main buffer.

Main and OTHER buffer text may be displayed simultaneously by splitting the screen into two windows using the WINDOW command.

3.20.1 Description

Press 0; the message hOther Editing input file" or, if no input file has been specified, hOther no input file" is displayed at the start of the message line whenever the secondary text is displayed:

- - - - 0 the rEd 1 t 1 n g input file

AgBin Block Celc Delete Execute Find -find --more--

The OTHER buffer allows you to edit a second file in the same way as the main buffer.

It is possible to display both the main and the OTHER text buffers by splitting the screen into two windows using the WINDOW command, then typing 0 to display the OTHER file in one window. In this case, switching from one window to the other results in switching from one text buffer to the other.

Each partition has a separate set of tags. A JUMP command is valid only within its own partition; it cannot jump to the other partition. Also, each partition has its own value for SET Leftcol. The Block buffer is common to allow moving text between partitions.

Press 0 to exit the OTHER buffer and return to the main buffer.

Count. Count has no meaning for the OTHER command.

3.21 AGAIN Command

To execute the AGAIN command, press A. It causes the last command or in some cases the last subcommand to be repeated.

In the following commands, AGAIN repeats the entire command, including subcom- mand arguments:

•PARAGRAPH

•(-)FIND, (?)REPLACE

In the following command, AGAIN repeats the entire command including subcom- mands, but without their arguments:

•HEX command

Count. Count is the count for the repeated command. The value of count given for the last command is ignored.

3.22 SET Command

The SET command allows you to set/reset several features that determine how AEDIT-86 will operate, e.g., if case (uppercase, lowercase) should be considered in the target string of a search command.

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.
