AEDIT-86 User's Guide

Macro Commands

Macro files are described later in this chapter.

The new macro definitions are added to the current set of available macros. If a macro in the new set has the same name as a macro already available, the new macro overrides the previous one. Configuration commands and SET commands are executed.

Press G; AEDIT-86 prompts-

----<HOME) to re-edit t-lecro file:

The name of the last macro file read (if any) is displayed to the right of the colon. Edit the macro filename, if required, then press <RETURN) .

You may insert an empty string as a filename by typing M(ACRO) G(et) <RETURN) to instruct AEDIT-86 to ""get" the present text buffer as a macro file.

When AEDIT-86 is invoked, the editor processes the initial macro file. The name of this file is taken from the macro control or, if this control is not specified, AEDIT- 86 changes the invocation file extension to <root) .MAC and processes it automat- ically. This means that you do not have to get the default macro file to execute the macros in it. However, you must get any other macro file before its macros are avail- able for execution.

Error. Any of the errors listed in Section B.4 may be issued during a MACRO Get. The error is displayed, the area causing the error is skipped, and processing continues.

Related Commands. The invocation controls MACRO, MACROSIZE

In8ert

The Insert subcommand causes all subsequent input, including function keys (e.g., <ESC) <RUBOUT) ) to be inserted in the text in macro form and not executed. It is used to change and correct macro files. For example, if you press <UP) in MACRO Insert, the character sequence \CU i$ inserted in the text. The macro definition may then be saved in a macro file. This command is terminated only by typing <CTRL-C ) .

Press I; AEDIT-86 prompts-

Control C to stop

In MACRO Insert, all keys are entered as is (e.g., F(lND) is entered as F). Thus, keys such as <HEX) or <ESC) do not perform a function but are inserted as their macro codes. The following are exceptions:

When <RETURN) is typed, it is not converted to \NL because the carriage

return is used to break macro definitions into more readable lines. Therefore, you must type \NL if <RETURN) is required in the definition.

If the backslash is not a lead-in character, it must be entered twice (\ \). However,

the backslash is not doubled when it is typed, which enables you to type \MM to terminate the macro or \NL for <RETURN) .

Type <CTRL-C) to terminate MACRO Insert mode.

Example. The following macro defines <CTRL-L) to mean jump to start of line. (Remember that what you type does not execute but is inserted in macro form.)

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.
