A string literal or anonymous string is a literal for a string value in the source code of a computer program. Modern programming languages commonly use a quoted sequence of characters, formally "bracketed delimiters", as in x = "foo", where , "foo" is a string literal with value foo. Methods such as escape sequences can be used to avoid the ...
Code statements have no terminating character other than a line ending (carriage return/line feed), and versions since 3 allow for multi-line statements for concatenation of strings or explicitly using the underscore character (_) at the end of a line [15] [16] A code comment is denoted by a single apostrophe (') character, like: ' This is a ...
For function that manipulate strings, modern object-oriented languages, like C# and Java have immutable strings and return a copy (in newly allocated dynamic memory), while others, like C manipulate the original string unless the programmer copies data to a new string.
The term string also does not always refer to a sequence of Unicode characters, instead referring to a sequence of bytes. For example, x86-64 has string instructions to move, set, search, or compare a sequence of items, where an item could be 1, 2, 4, or 8 bytes long.
ATTRB - Character attributes; BOX (x1,y1)-(x2,y2) - Draws a rectangle (the top left pixel is (0,0) BOXF (x1,y1)-(x2,y2),color - Fills a rectangle with the given color (optional, if not given use the current pen color). Negative colors lead to filling with the requested color as the background one. CLS - Clear screen
HTML and XML provide ways to reference Unicode characters when the characters themselves either cannot or should not be used. A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name. A numeric character reference uses the ...

String datatypes have historically allocated one byte per character, and, although the exact character set varied by region, character encodings were similar enough that programmers could often get away with ignoring this, since characters a program treated specially (such as period and space and comma) were in the same place in all the ...
