variable, designate location in memory, a place in memory, is called variable; data types are variable, but variant data type is the only one WHICH can change data types, e.g. integer is not variant, e.g. string is not variant; If NOT declaring variable, it becomes a variant, and the variant is changeable among data types ... ;

Before writing above formula, 1st to understand 1.1, 1.2, swap, therefore 2.1 for each d, concurrency at 2.2, and then 4.32 (i.e. interval e.g. enumerator); 2nd to understand (line*actions)!/(!actions) line; 3rd to understand any type; 4th to understand any type of artificial intelligence (array; record) as both reference and function; 5th to develop interval for each domain e.g. artificial intelligence (array; record) with start Square root 2; length integer; (unit) enumerator; Therefore, any type ... ; approx. 15+ years old info, e.g. dim in Basic programming language; with dim, any type of ... ;

i = i + 1, i.e. increase method;  i = i - 1, i.e. decrease method; WHERE i is a defined variable; And, notice that based10 number one is not variable; Compiler dependent based10 number one is very interesting because number in displacement might vary with time ... ; counter (e.g. count) and conditional statement (e.g. operator) can control WHICH method (e.g. decrease method, increase method) ... ;

Variables can be classified into dependent variable AND independent variable; In xy plane, in rectangular coordinates, X axis' abscissa can be plotted as independent variable AND Y axis' ordinate becomes dependent variable; In polar plane, radius r from origin can be plotted as independent variable as distance AND angle q becomes dependent variable;

%PATH% ; Since MS-DOS, PC-DOS era in 1990, %PATH% has been used to initialize especially for sharing / limiting of directories within a file system; Volumes and drive letters are partition dependent, and notice that "partition dependent" provides file system independent [which mean diff file format, diff file system]; System management skill and knowledge can really make vulnerable to any working environment because important / classified / private / public / top-secret levels of working data are all within the system variable; To protect such %PATH% system variable, OS provides several containers with do(s) and dont(s) ... ;

%USERPROFILE%; inside desktop.ini file, a sector a.k.a. a brunch such as [.ShellClassInfo] may have been cached a.k.a. cache: as UICLSID = { 32 alphanumeric }; And notice that in 2008, beyond 12 alphanumeric such as file:///, %USERPROFILE%, ... have already prompted at the same level ... ;

%USERPROFILE% ; i.e. %TEMP% = %USERPROFILE%\Local_Settings\Temp; %TMP% = %USERPROFILE%\Local_Settings\Temp; User;

var , variable in programming language; It is almost impossible to know all, and recommends not to know all, because trillions dollars businesses in computing ... ; var variable may vary along with wafer design, pin level design, compilers' character mapped algorithm design, and so on. Therefore, var is variable in common, but somehow in wafer level system programming var might not be variable [ for example: consider the system level Java code such as var Trigger=NavYes&&!Opr?Par:Bod ] so that some codes cannot be changed ... ; RAP music's usage = "crunching numbers" ;

%Version% ; DOS vs. NT;

%WINBOOTDIR% ; Else, %OS%;

%windir% ; i.e. %windir% = C:\WIN_OS_name;

%WINDIR% ; Because, %BIN% is machine dependent; If %BIN% is machine independent and non-Windows system, protocol must exist to use the system variable;

%Windir% ; In Vista OS, concerning UAC, also see: %ProgramFiles%;

%YELLOWISH_VARIATION% ; yellowish variation is measured in mm (millimeter) and yellowish variations define distance among planets; IFF Dark Energy Engineering ( DEE), yellowish variation indicates not only distance, but also directional ... ;

in the early 21st century, yellowish variation is one of the highest technologies WHICH has been a.k.a. Solar Sail Method; this DOMAIN 's imaginary hyper space crafts went very very very far away in distance in our universes, and already mapped not only our earth, but also our universes;
