Storing Data into Variables

Each black letter is associated with a key and a unique variable. The letter keys
are automatically active when needed. (The A..Z annunciator in the display
confirms this.)

Note that the variables, X, Y, Z and T are different storage locations from the
X–register, Y–register, Z–register, and T–register in the stack.
