T0.0000 “Oldest” number

Z0.0000

Y0.0000

X 0.0000 Displayed

The most "recent" number is in the X–register: this is the number you see in the display.

In programming, the slack is used to perform calculations, to temporarily store intermediate results, to pass stored data (variables) among programs and subroutines, to accept input, and to deliver output.

The X–Register Is in the Display

The X–register is what you see except when a menu, a message, or a program line is being displayed. You might have noticed that several function names include an x or y.

This is no coincidence: these letters refer to the X– and Y–registers. For example, z(raises ten to the power of the number in the X–register (the displayed number).

Clearing the X–Register

Pressing zb{º} always clears the X–register to zero; it is also used to program this instruction. The †key, in contrast, is context–sensitive. It. either clears or cancels the current display, depending on the situation: it acts like zb{º} only when the X–register is displayed. aalso acts like z b {º} when the X–register is displayed and digit entry is terminated (no cursor present). It cancels other displays: menus, labeled numbers, messages, equation entry, and program entry.
