1In computer programming, there are different ways of using data items. A [blank_start]global variable[blank_end] is a variable that can be edited throughout the entire program whereas a [blank_start]local variable[blank_end] can only be used in the sub-program in which it is declared. When data is used in more than one sub-program, a [blank_start]parameter[blank_end] can be passed by value or reference. When a [blank_start]value[blank_end] parameter is used, a copy is passed into a sub-program and the original data item is unchanged whereas, with a [blank_start]reference[blank_end] parameter, the actual data item is passed into a sub-program, can be edited or changed and the changes are passed out.
