3.10 FIND Command

The FIND command searches forward from the current cursor position to the end of the file for a string of characters and positions the cursor after the next occurrence of the string.

3.10.1 Description

Press F; AEDIT-86 prompts-

<HOME) to re-edlt

F 1 n d { mode} H targeLstring II

The last target string (if any) is displayed within quotes. mode refers to the SET options currently in effect that may influence the FIND command.

Note that pressing <RETURN) when specifying a target string inserts a carriage return/line feed into the target string and adds the RETURN symbol, (nl), to the prompt line. You must press (ESC) to complete the string specification and execute the FIND command.

The cursor is placed immediately after the next occurrence of the target string. If the string is not found, the message "not found: "target string" " is displayed in the message line and the FIND command is marked as failed.

The following attributes affect operation of the FIND command:

Case - consider case of Find target

Showfind - list lines or multiple finds

K_token - find only token strings

Case, Showfind, and K_token refer to features set using the SET command, which is described later in this chapter.

Case refers to upper- or lowercase letters. If Case is no, upper- and lowercase letters are equivalent.

If Showfind is yes, each line that contains the target string is displayed.

The Token is the argument between delimiters. Token characters are all characters that are not delimiters. For example, if you want to find the word is in the preceding paragraph, but not the is in displayed. If SET K_token is yes, each occurrence of the word is is found because it is enclosed in delimiters.

The string -{ mode} contains an abbreviation for the. features, Case (Cs), Token (Tk), and Showfind (Sh). The abbreviation is displayed only if the specified feature is set to yes. If more than one feature is yes, the features are separated by a blank.

The following are examples of mode:

FIND -{ Cs} " ... "

Consider case = yes

FIND

-{ Tk Sh} " " Token and Showfind = yes

FIND

-{ } ....."

No option is set

To abort a (- )FIND command, press (CTRL-C).

The message "found: count" is displayed when the command is complete.

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.
