Macro Commands

These macros can be defined interactively using the MACRO Create command. For example. the first macro can be created by entering the following commands:

~ACRO) I<reate

Macro name:

l ET) I.eftcol

(to terminate macro deJfinliticm

After you define these macros, typing a right square bracket (]) at main command level or <MEXEC ) ] in INSERT or XCHANGE mode sets Leftcol one position to the right of its current setting; typing a left square bracket (]) at main command level or <MEXEC ) [ in INSERT or XCHANGE mode sets Leftcol one position to the left of its current setting.

5.10.2 Example 2

The folJowing single-character macros, named dot (.) and comma (,) find the next occurrence of the target string, or find the previous occurrence of the target string, respectively.

M. \BRf \BR \MM

M, \BR- \BR \MM

These macros can be defined interactively using the MACRO Create command. For example, the first macro could be created as follows:

IACRO) I<reate

Macro name:

I IND _

(to termmate the macro definition)

After you define these macros, typing a dot (.) at main command level or <MEXEC) followed by a dot in INSERT or XCHANGE modes finds the next occurrence of the target string; typing a comma (,) at main command or <MEXEC ) followed by a comma in INSERT or XCHANGE modes, finds the previous occur- rence of the target string.

5.10.3 Example 3

It is often desirable to use visual breakpoints in programs. For example, you can use comment lines filled with hyphens to separate procedures in a language. The follow- ing macro creates a break line:

M® \ BRI(* - - - - - - - - - - - - - - - - - - - - *) \ NL \ BR \ MM

You can create this macro interactively with the following commands:

After you define this macro, typing @ at main command level, or <M EXEC) @ in INSERT or XCHANGE mode inserts the break line at the current cursor position in text.

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.
