In imperative languages, variables bind to relative locations in memory that can store values.

When storing small keys and values, the space overhead of the pointer in each entry record can be significant.

A set is an abstract data structure that can store certain values, without any particular order, and no repeated values.

A set can store certain values, without any particular order, and with no repeated values.

Due to storing identities and values together, knots cannot be historized.

The operation is used both to initialize the stack, and to store values to it.

Then, after processing X[i], the algorithm will have stored values in two arrays:

They can also be used to store temporary values for reference later in a shell script.

A tuple can be used to store values only when the number of values is known at design-time and stays constant throughout execution.

Advanced, Financial, and Programming modes present features for storing and retrieving values labeled as variables.
