When creating software it is often possible to represent an entire set of symbols, with only one symbol. This can involve a set of numbers, words, formulas, or a string of computer code, which is represented by one symbol. This is especially useful if the set represents a very long string of text, code, or series of numbers, that must be repeated a number of times to create computer software. This simple concept is demonstrated on this website with online JavaScript software. When I was experimenting with this software, I was able to use ONE letter to represent, transmit, and display thousands of words.

The JavaScript software presented below, functions online and it was created to demonstrate a simple computing concept, where one symbol can be used to represent an entire set of symbols. To see this demonstration scroll down until you see the JavaScript software that is embedded in this webpage. (The software starts with a yellow section that contains additional instructions.)

The software contains ten boxes, framed in blue, with a white input field on the left. Enter A in the input fields. Each time the letter A is entered the same set of words will be displayed. After this, you can repeat the experiment with the letters B, and C, both of which represent another set of symbols. This concept can be represented symbolically as follows:

A={Set of word represented by A }

B={Set of word represented by B}

C={Set of word represented by C}

The important concept here is the meaning of the letters A, B, and C have been essentially predefined, to represent specific sets of symbols, which comprise the messages that you will see when you enter A, B, and C. You can change these messages, by scrolling to the bottom of the software, where you will see three boxes framed in red. The first input box defines the set of symbols for A, the second box for B and the third for C. You can delete these messages and enter your own words. When this is done the meaning of A, B and C are read the fine as follows

A={Set of words you entered in input Box-One}

B={Set of words you entered in input Box-Two }

C={Set of words you entered for input Box-Three }

This software was designed for you to experiment with, and to demonstrate a simple computing concept, where ONE SYMBOL can be used to represent an ENTIRE SET OF SYMBOLS. To use this software, you can start by entering the letter A in the TEN boxes presented four paragraphs below. Each time you enter the letter A you will see three or four lines of text that was transmitted from SET A. Then repeat the above with the letters B and C. When this is done you will see the text associated with SETS B and C. You can also enter different letters in each box.

OPTIONAL: If you want to change the text in SETS A, B, and/or C, scroll all the way down until you see three input boxes framed in red. Then click on an input box, and delete the message. After this you can enter your own message. If you enter a message more than three or four lines in length, you must left click on the yellow display boxes and SCROLL DOWN WITH THE ARROW KEYS, to see the entire message. (An interesting experiment is to see how many words you can enter, into one of these input boxes. The maximum amount of text that you can enter will be determined by your computer and the browser you are using. With my system, I was able to enter OVER 25,000 words in one of the boxes, and it was successfully transmitted to the ten yellow display boxes with no difficulties.)

NOTE: If you want to enter the same letter in all of the ten input boxes, you can do this simultaneously, by entering the letter in the white box, presented below.

If you want to enter letters individually in each of the following ten input boxes, you can leave the above box blank. If there is a letter in the box above, it will be overwritten by letters you enter in the input boxes below.
