Editing Commands

The current values for indent, left, and right are displayed to the right of the colon separated by commas. The first number sets the indentation, the second the left margin, and the third the right margin. Indent may be set at any value from 0-253; left, from 0-253; and right, from 1--254. The value of the right margin must be greater than the indentation and the left margin. When entering the values, separate them by one or more blanks or CJ comma. The values of aJ) three numbers are absolute and offset from position O. The default values are 4, 0, and 76.

Press <ESC) or < RETURN) to execute the commCJnd and return to main command level.

To set indent to 0, left to 5, and right to 70, type-

8ET) I<argin) - 5, 70 <RETURN>

To reset the left margin to 2, type-

I<ET) I<argin) 2 <RETURN>

Related Commands. PARAGRAPH, SET Autonl

Notab

To execute the. Notab option, press N. This option instructs the editor to replace inserted tabs with the appropriate number of blanks. It prompts-

insert blanks for tabs'? (y or (n])

•If y, blanks are inserted instead of tabs whenever you press the <TAB) key in the INSERT or XCHANGE mode.

•If n, this option is turned off.

Note that this option does not affect tabs that are entered using the < HEX) prefix ( (HEX) 09).

Related Commands. SET Tab

Radix

To execute the Radix option, press R. This option allows you to determine the radix (base) in which an AEDIT-86 variable will be inserted in the text. It prompts-

- - - - cur r e n t Ra d i x: radix

Alpha Binary DeCimal Hex Dc t a I

This option affects values inserted or exchanged by the Fetch operation < FETN ) (described in Chapter 6). The Radix default is Decimal.

For more on Radix, see Chapter 6.

Related Commands. INSERT, XCHANGE

Showfind

To execute the Showfind option, press S. It is used to display all lines containing the target string in a FIND/REPLACE command. It prompts-

list lines on multiple finds'? (y or (n])

•If y, when you execute a FIND or (?)REPLACE command, the screen is cleared, and each text line that contains the target string is displayed on the screen. Each string is displayed on a separate line. When the screen is full, the message "hit space to continue" is displayed.

•If n, the FIND and (?)REPLACE commands execute as usual. but the screen is not cleared, and text lines that contain the string are not displayed on the screen.

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.
