138 TI-Nspire™ Reference Guide
230 Dimension
A list or matrix index is not valid. For example, if the list {1,2,3,4} is stored in L1, then L1[5] is a dimension error
because L1 only contains four elements.
235 Dimension Error. Not enough elements in the lists.
240 Dimension mismatch
Two or more arguments must be of the same dimension. For example, [1,2]+[1,2,3] is a dimension mismatch
because the matrices contain a different number of elements.
250 Divide by zero
260 Domain error
An argument must be in a specified domain. For example, rand(0) is not valid.
270 Duplicate variable name
280 Else and ElseIf invalid outside of If...EndIf block
290 EndTry is missing the matching Else statement
295 Excessive iteration
300 Expected 2 or 3-element list or matrix
310 The first argument of nSolve must be an equation in a single variable. It cannot contain a non-valued variable
other than the variable of interest.
320 First argument of solve or cSolve must be an equation or inequality
For example, solve(3x^2-4,x) is invalid because the first argument is not an equation.
345 Inconsistent units
350 Index out of range
360 Indirection string is not a valid variable name
380 Undefined Ans
Either the previous calculation did not create Ans, or no previous calculation was entered.
390 Invalid assignment
400 Invalid assignment value
410 Invalid command
430 Invalid for the current mode settings
435 Invalid guess
440 Invalid implied multiply
For example, x(x+1) is invalid; whereas, x*(x+1) is the correct syntax. This is to avoid confusion between implied
multiplication and function calls.
450 Invalid in a function or current expression
Only certain commands are valid in a user-defined function.
490 Invalid in Try..EndTry block
510 Invalid list or matrix
550 Invalid outside function or program
A number of commands are not valid outside a function or program. For example, Local cannot be used unless it
is in a function or program.
560 Invalid outside Loop..EndLoop, For..EndFor, or While..EndWhile blocks
For example, the Exit command is valid only inside these loop blocks.
565 Invalid outside program
