Flags are generally found as members of a defined data structure (such as an entry in a database) and the meaning of the value contained in a flag will generally be defined in relation to the data structure to which it belongs.In many cases, the binary value of a flag will be to represent one of several possible states or categories In other cases, binary values could represent one or more attributes in a bit field, usually related to skills or permissions, such as "can be written" or "can be removed." However, there are many other possible meanings that can be assigned to the values in the flags.A common use of flags is to mark or designate data structures for future processing.
Within microprocessors and other devices Logically, flags are generally used to control or indicate the intermediate or final state or result of different operations.Generally, microprocessors have, for example, a state register that is made up of flags and flags are used to indicate various post-operation conditions., such as when there is an arithmetic overflow.Flags can be used in subsequent operations, as in conditional processing jump instructions.
