# Creating and Saving Files

One of the best features of the BASIC language that Sinclair designed into the ZX-81 (TS-1000) is its ability to SAVE all of its variables, including arrays, in the normal course of SAVEing the program onto cassette tape and reloading the variables along with the program LOAD. This allows us to transfer a file, in the form of data, along with the program to manipulate or interpret it, to and from tape in a single motion.
