Macro Commaads

AEDIT-86 User's Guide

5.4.1 Description

Press [count] E; AEDIT-86 prompts-

----<HOME) to re-edlt Macro name:

The name of the last macro specified (for MACRO Create, MACRO Save, or EXECUTE) is displayed to the right of the colon. Type a macro name followed by < ESC) or < RETURN). If the macro exists, it is executed.

If the busy/waiting indicator is active, the prompt line displays -!!-when a macro is being executed. This is important in single-character macro execution where there may not be any other indication that a macro is still executing.

The macro terminates when it has been executed the specified number of times or failed. Section 5.8 describes macro execution termination in more detail.

Macro activation may be nested up to eight levels.

Type a < CTRL-C) to force termination of macro execution.

Errors

•'''no such macro" is displayed if the macro specified does not exist.

•6'macro nesting too deep" is displayed if you attempt to nest macros to more than eight levels.

Count. The EXECUTE command accepts any count.

5.5 Macros and AEDIT-86 Variables

When AEDIT-86 variables are referenced during MACRO Create, the actual varia- ble value is fetched for the current activation of the macro, and a reference to this variable is inserted into the macro definition. The use of AEDIT-86 variables provides a primitive way to simulate passing a parameter to a macro. See Section 6.3 for more details.

5.6 Single-Character Macros

You can write macros with single-character names. You can activate a single- character macro by simply typing its name if this character has no other function in the context from which it is being activated. Single-characters that can be used as macro names are referred to as "free" characters, e.g., L, U, Z, +, !.

Single-character macros can be activated in the following ways:

•Using the EXECUTE command at main command level (as in the case for all macros).

•By pressing the macro character preceded by the <MEXEC) key.

•By pressing the key itself, if the key is "free," that is-

In INSERT and XCHANGE modes: all nonconfigured control characters. The

following control characters also cannot be used as macros in this way: <CTRL-M) « RETURN», <CTRL-I) « TAB) ), and <CTRL-J) (line feed).

In main command levels: the same as for INSERT and XCHANGE modes with

the addition of all printable characters that are not used as AEDIT-86 commands (e.g., +, $, U, etc.).

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.
