Subscripted variable A variable followed by a subscript in brackets, designating an array element
Array script A value or expression enclosed in brackets after the array name, specifying which array element to access
Pop remove the top element of a stack
Push insert a new element at the top of the stack
Parallel arrays two or more arrays with the same number of elements used for storing related information about a collection of data objects
Enumerated type a data type whose list of values is specified by the programmer in a type declaration

Seed seed for a random number generator. An initial value used in the computation of the first random number.
