- * 		- *

- * 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 - *

- * 		- *

- * Invalid semicolon - *

- * 		- *

- * Not used - *

- *
- *

- * 507 - *

- * 		- *

- * 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. - *
