Tabs

To execute the Tabs option, press T. This option allows you to set tabs. It prompts-

----(HOME) to re-edit

T I b is: 4

The prompt line lists the current tab settings. If you want only to inspect the tab settings, type (CTRL~C) to return to main command level.

To enter tabs, type a list of decimal numbers separated by at least one blank or a comma. The numbers must be specified in increasing order, from }-253. Changing the tab settings does not change the file contents, but it may affect its display on the screen.

The default tab settings are every fourth position, i.e., 4, 8, 12....

The difference between the last two numbers specified for tabs is repeated, up to 253.

For example-

4sets tabs at 4, 8, 12, 16, ...

5,6,10 sets tabs at 5, 6, 10, 14, 18, ...

o sets tabs at 4, 8, 12, 16, ...

NOTE

-Columns start at 0, not 1. Therefore, FORTRAN tabs should be 6,} 0, not 7,11.

Errors. hbad tabs" is displayed if you attempt to set an illegal tab.

Viewrow

To execute the Viewrow option, press V. This option allows you to select a viewrow for rewriting the screen. It prompts-

row for VIew: 5

The current viewrow setting is displayed to the right of the colon. Type the number of the row on which you wish the cursor to be positioned by the VIEW command. This value must be between 0 and the text size -I. If, for example, your screen size is 25 rows, then text size is 23 (25 minus the message line and the prompt line). Therefore, in this case, the legal values are 0-22.

The default viewrow is the terminal length divided by 5, which means 5 on most terminals.

If the screen is split using the WINDOW command, the view row is determined separately for each window by a formula based on the current view row and the window size.

Errors. hbad View row" is displayed if viewrow is set to a value greater than text size -1.

3-22

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.
