Diagnosing an Error
The TI-83 Plus detects errors while performing these tasks.
• Evaluating an expression
• Executing an instruction
• Plotting a graph
• Storing a value
When the TI-83 Plus detects an error, it returns an error message as a
menu title, such as ERR:SYNTAX or ERR:DOMAIN. Appendix B describes
each error type and possible reasons for the error.
• If you select 1:Quit (or press y 5 or ‘), then the home
screen is displayed.
• If you select 2:Goto, then the previous screen is displayed with the
cursor at or near the error location.
Note: If a syntax error occurs in the contents of a Y= function during program
execution, then the Goto option returns to the Y= editor, not to the program.
