+ *
+ * Message
+ *
+ * |
+ *
+ *
+ * Explanation
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 501
+ *
+ * |
+ *
+ *
+ * Invalid character
+ *
+ * |
+ *
+ *
+ * Character in a formula is not valid, for example, "=1Eq" instead of
+ * "=1E2".
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 502
+ *
+ * |
+ *
+ *
+ * Invalid argument
+ *
+ * |
+ *
+ *
+ * Function argument is not valid, for example, a negative number for the root
+ * function.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 503
+ *
+ * |
+ *
+ *
+ * Invalid floating point operation
+ *
+ * |
+ *
+ *
+ * Division by 0, or another calculation that results in an overflow of the
+ * defined value range.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 504
+ *
+ * |
+ *
+ *
+ * Parameter list error
+ *
+ * |
+ *
+ *
+ * Function parameter is not valid, for example, text instead of a number, or a
+ * domain reference instead of cell reference.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 505
+ *
+ * |
+ *
+ *
+ * Internal syntax error
+ *
+ * |
+ *
+ *
+ * Not used
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 506
+ *
+ * |

+ * |
+ *
+ *
+ * Error: Pair missing
+ *
+ * |
+ *
+ *
+ * Not used
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 508
+ *
+ * |
+ *
+ *
+ * Error: Pair missing
+ *
+ * |
+ *
+ *
+ * Missing bracket, for example, closing brackets, but no opening brackets
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 509
+ *
+ * |
+ *
+ *
+ * Missing operator
+ *
+ * |
+ *
+ *
+ * Operator is missing, for example, "=2(3+4) * ", where the operator
+ * between "2" and "(" is missing.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 510
+ *
+ * |
+ *
+ *
+ * Missing variable
+ *
+ * |
+ *
+ *
+ * Variable is missing, for example when two operators are together
+ * "=1+*2".
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 511
+ *
+ * |
+ *
+ *
+ * Missing variable
+ *
+ * |
+ *
+ *
+ * Function requires more variables than are provided, for example, AND() and
+ * OR().
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 512
+ *
+ * |
+ *
+ *
+ * Formula overflow
+ *
+ * |
+ *
+ *
+ * Compiler: the total number of internal tokens, (that is, operators,
+ * variables, brackets) in the formula exceeds 512. Interpreter: the
+ * total number of matrices that the formula creates exceeds 150. This includes
+ * basic functions that receive too large an array as a parameter (max. 0xFFFE,
+ * for example, 65534 bytes).
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 513
+ *
+ * |
+ *
+ *
+ * String overflow
+ *
+ * |
+ *
+ *
+ * Compiler: an identifier in the formula exceeds 64 KB in size.
+ * Interpreter: a result of a string operation exceeds 64 KB in size.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 514
+ *
+ * |
+ *
+ *
+ * Internal overflow
+ *
+ * |
+ *
+ *
+ * Sort operation attempted on too much numerical data (max. 100000) or a
+ * calculation stack overflow.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 515
+ *
+ * |
+ *
+ *
+ * Internal syntax error
+ *

+ * Not used
+ *

+ *
+ *
+ * |
+ *
+ * 516
+ *
+ * |
+ *
+ *
+ * Internal syntax error
+ *
+ * |
+ *
+ *
+ * Matrix is expected on the calculation stack, but is not available.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 517
+ *
+ * |
+ *
+ *
+ * Internal syntax error
+ *
+ * |
+ *
+ *
+ * Unknown code, for example, a document with a newer function is loaded in an
+ * older version that does not contain the function.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 518
+ *
+ * |
+ *
+ *
+ * Internal syntax error
+ *
+ * |
+ *
+ *
+ * Variable is not available
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 519
+ *
+ * |
+ *
+ *
+ * No result (#VALUE is in the cell rather than Err:519!)
+ *
+ * |
+ *
+ *
+ * Formula yields a value that does not corresponds to the definition, or a cell
+ * that is referenced in the formula contains text instead of a number.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 520
+ *
+ * |
+ *
+ *
+ * Internal syntax error
+ *
+ * |
+ *
+ *
+ * Compiler creates an unknown compiler code.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 521
+ *
+ * |
+ *
+ *
+ * Internal syntax error
+ *
+ * |
+ *
+ *
+ * No result.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 522
+ *
+ * |
+ *
+ *
+ * Circular reference
+ *
+ * |
+ *
+ *
+ * Formula refers directly or indirectly to itself and the iterations option is
+ * not selected under Tools - Options - Table Document - Calculate.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 523
+ *
+ * |
+ *
+ *
+ * The calculation procedure does not converge
+ *
+ * |
+ *
+ *
+ * Financial statistics function missed a targeted value or iterations of
+ * circular references do not reach the minimum change within the maximum steps
+ * that are set.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 524
+ *
+ * |
+ *
+ *
+ * invalid references
+ * (instead of Err:524 cell contains #REF)
+ *
+ * |
+ *
+ *
+ * Compiler: a column or row description name could not be resolved.
+ * Interpreter: in a formula, the column, row, or sheet that contains a
+ * referenced cell is missing.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 525
+ *
+ * |
+ *
+ *
+ * invalid names (instead of
+ * Err:525 cell contains #NAME?)
+ *
+ * |
+ *
+ *
+ * An identifier could not be evaluated, for example, no valid reference, no
+ * valid domain name, no column/row label, no macro, incorrect decimal divider,
+ * add-in not found.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 526
+ *
+ * |
+ *
+ *
+ * Internal syntax error
+ *
+ * |
+ *
+ *
+ * Obsolete, no longer used, but could come from old documents if the result is
+ * a formula from a domain.
+ *
+ * |
+ *
+ *
+ * |
+ *
+ * 527
+ *
+ * |
+ *
+ *
+ * Internal overflow
+ *
+ * |
+ *
+ *
+ * Interpreter: References, such as when a cell references a cell, are
+ * too encapsulated.
