  

SOLVE (include EQN and PGM mode)cannot find the

 

root of the equation using the current initial guesses (see

 

page ). These conditions include: bad guess, solution

 

not found, point of interest, left unequal to right. 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 .) 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.

 

The calculator is running an equation or program (other than a SOLVE or FN routine).

Attempted to execute  variable or  d variable without a selected program label. This can happen 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.



The calculator is solving an equation or program for its

 

root. This might take a while.



Attempted to calculate the square root of a negative

 

number.
