ASCII code

Cursors of different shapes and sizes can be designed easily by the microcomputer user through simple programming, such as using the BASIC commands GET and PUT. The movement of the user-created cursor is controlled through the use of the INKEY function and by testing the ASCII codes of the keyboard keys. 

Using a Terminal. Dial-up terminals may also be used to access a vendor s databases however, the terminal, personal computer, word processor, or microcomputer must all be compatible with specific functionaHties. Eor example in order to access the DIALOG service these must all be TTY compatible have ASCII coding and be compatible for asynchronous transmission in full-duplex mode for communication through DIALNET,... 

Serial output ports (RS-232) are usually provided for serial transmission of data— usually in ASCII code as previously shown in Fig. 5. 

The simplest of the formats used to transfer data into word processing applications is the ASCII (.ASC). ASCII is a standard set of 128 binary codes used by all computers to represent all the characters presented on the normal or shifted keyboard plus control codes, originally intended for use on teletypewriters. These code allow us to display lower case leters, capital letters, numbers, and punctuation marks, but formatting codes for underline, boldface, and italics are not included in ASCII, and are removed in converting formats. ASCII files have space-separated code and can be sent out over a modem or a serial cable to another computer and applications importing ASCII code. 

The next type of standard output is the spreadsheet. These file formats use comma-separated ASCII code, but also add calculation information and addressing information for the columns and rows they occupy. The simplest of these are. DIF files, which originated to allow information transfer between VisiCalc worksheets in the Apple II computer and have been retained as a standard format.. WK files are Lotus-1,2,3 formats and. XLS are Microsoft Excel formats that have become spreadsheet standards, allowing transfer of data, calculations, addresses, and macro programs. 

R 18] [A 3] As in every macro-scale chemical plant, all process I/O operations are visualized in the graphical user interface (Figure 4.62) The process data can be recorded as a function of time and also exported in ASCII code (Figure 4.63). 

In Excel for Windows, the characters are obtained by holding down the ALT key and typing the four-digit ASCII code for the character, using the numeric keypad. The range of useful characters obtainable in this way is rather limited. Table 1-3 gives some characters for Macintosh for characters obtained using Arial, one standard font for Excel 2000 for Windows, use the ASCII codes shown in parentheses in Table 1-3. 

For Macintosh. Four-digit ASCII codes in parentheses are for Windows.

A code is used for converting one type of symbolism to another. For example, the ASCII code of computers specifies that each letter of the keyboard has a numerical equivalent - "A" is equivalent to ASCII code 65, etc. 

The term bit is a contraction of /binary dig/t. A convenient unit in computer applications is a grouping of 8 bits, like bbbb bbbb, known as a byte. Each byte can represent up to 256 binary units of information. Since computers can only understand numbers, ASCII (American Standard Code for Information Interchange) is used to represent letters and other nonnumeric characters. For example, ASCII codes 65 to 90 stand for the uppercase letters, A to Z, while 97 to 122 stand for lowercase, a to z. ASCII code 32 stands for a space. As an illustration ...

In the most recent iteration of the feedback loop which relates molecular structure to solid-state device performance, the fast bistable [2]rotaxane 11" has been superseded " by the modified and improved version shown in Fig. 1.15, namely, the [2]rotaxane The impetus for this iteration was at least two-fold (1) to produce a molecular switch in which the bistable rotaxane starts off exclusively in one, and only one, of its two possible co-conformations and (2) to incorporate into this all-or-nothing switch enhanced oxidative stability by removing all of the phenolic residues from the hydrophilic stopper. The rotaxane, which was obtained (Fig. 1.15) by the now well-established templation protocol, has been incorporated by the familiar fabrication procedures into an 8 x 8 crossbar device (Fig. 1.16(a)). Fig. 1.16(b) demonstrates one of these 64-bit devices in operation with the exception of one of the wires, i.e., 56 out of the 64 bits can be switched. This device has been used to store (Fig. 1.16(c)) the letters DARPA in ASCII code the lifetime of the switch-closed state of this devices is about 10 minutes. The proposed electromechanical switching mechanism for the bistable [2]rotaxane which is outlined in Fig. 1.17, merits comparison with that already discussed in Fig. 1.16 for the bistable [2]rotaxane In the case of it is proposed that oxidation of the TTF unit to its radical cation (TTF ) occurs when a +2 V bias is applied across the bistable [2]rotaxane and the tetracationic cyclophane moves to encircle the...

However, the power of any particular screen reader is in the degree to which the other capabilities dictated by the use of the GUI are achieved. The fundamental differences in the ways that a text-only command-line interface (CLI) and a GUI provide output to the video screen present access problems for persons who are blind. These are related to both the ways in which internal control of the computer display is accomplished and the ways in which the GUI is employed by the computer user (Boyd et al., 1990). The CLI-type interfaces use a memory buffer to store text characters for display. Since all the displayed text can be represented by ASCII code, it is relatively easy to use a software program and to divert text from the screen to a speech synthesizer or Braille display. However, this type of screen reader is unable to provide access to charts, tables, or plots because of their graphic features. This type of system is also limited in the features that can be used with text. For example, features such as size, shape, and font or alternative graphic forms are not captured in standard ASCII text code.
