The calculator responds to certain conditions or keystrokes by displaying a message. The ¤symbol comes on to call your attention to the message. For significant conditions, the message remains until you clear it. Pressing or b clears the message; pressing any other key clears the message and executes that key's function.

A running program attempted to select a program label (/label) while an integration calculation was running.

A running program attempted to integrate a program (

≥ G variable) while another integration calculation was running.

A running program attempted to solve a program while an integration calculation was running.

The catalog of variables ( {Y{#} ) indicates no values stored.

The calculator is executing a function that might take a while.

Allows you to verily clearing the equation you are editing. (Occurs only in Equation–entry mode.) Allows you to verify clearing all programs in memory. (Occurs only in Program–entry mode.)

Attempted to divide by zero. (Includes Tif Y–register contains zero.)

Attempted to enter a program label that already exists for another program routine.

Indicates the "top" of equation memory. The memory scheme is circular, so ! ! is also the "equation" after the last equation in equation memory.
