Attempted to refer to a nonexistent program label (or line number) with V,V, X, or {}. Note that the error % !! can mean

„you explicitly (from the keyboard) called a program label that does not exist; or

„the program that you called referred to another label, which does not exist.The catalog of programs ( {Y{} ) indicates no program labels stored.

SOLVE cannot find the root of the equation using the current initial guesses (see page D–8). A SOLVE operation executed in a program does not produce this error; the same condition causes it instead to skip the next program line (the line following the instruction

# variable).

Warning (displayed momentarily); the magnitude of a result is too large for the calculator to handle. The calculator returns ±9.99999999999E499 in the current display format. (See "Range of Numbers and Overflow" on page 1–16.) This condition sets flag 6. If flag 5 is set, overflow has the added effect of halting a running program and leaving the message in the display until you press a key.

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

Attempted to execute # variable or  d variable without a selected program label. This can happen only the first time that you use SOLVE or FN after the message & , or it can happen if the current label no longer exists.

A running program attempted to select a program label (/label) while a SOLVE operation was running.

A running program attempted to solve a program while a SOLVE operation was running.

A running program attempted to integrate a program while a SOLVE operation was running.
