AEDIT·86 User's Guide

Note that:

•QUIT Abort and QUIT Exit relate to the entire AEDIT-86 session, i.e., to both the current file and the secondary file. QUIT Init, QUIT Update, and QUIT Write relate only to the file you are currently editing.

•An output file indicated by the TO clause can be specified for a file in either the invocation line or at the QUIT Init command. Only the subcommands Update and Exit relate to this output file; Write does not.

3.24.2Filename Not Specified

If you are editing a new file and have not yet specified a filename, the Exit and Update subcommands are not available (both subcommands require a filename). The AEDIT-86 prompt is altered as follows:

----no input f11e

Abort

In1t

Wr 1 t e

The subcommands function the same as discussed above.

3.25 PARAGRAPH Command

To invoke the PARAGRAPH command, press P. A paragraph is defined as one or more nonempty lines preceeded by and followed by an empty (or blank) line. The PARAGRAPH command reformats a paragraph using the values set for indent and left and right margin in the SET Margin command. Reformatting means rearranging or adjusting the words within a· paragraph between the right and left margins. A word is defined as· a sequence of characters surrounded by white spaces (i.e., space, tab, line feed, or carriage return). The default is to reformat one paragraph.

NOTE

The PARAGRAPH command execution starts by indentifying the begin- ning of the current paragraph. AEDIT-86 searches backward for an empty line; then, the end of the paragraph is found by searching forward for an empty line. This implies that if your file has no empty lines, PARAGRAPH will process the entire file as one paragraph, wherever the cursor is currently positioned in the file.

3.25. 1 Description

Move the cursor to any position in the paragraph to be reformatted.

Press P; AEDIT-86 prompts-

F 1 I I Justify

To specify an option, press the initial letter of that option.

Count. Count defines the number of consecutive paragraphs to reformat.

Related Commands. SET Margin

Fill

Press F to perform filling. This means that the white space sequences are reduced to one blank, and every blank after a sentence terminator (e.g., period, question mark) is extended to two blanks. Words are moved to fill the line between the right and left

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.
