| Format: |
AValid(ArrayElem, N) |
| Parameters: |
| ArrayElem |
| Required. An array element. The subscript(s) for the array may be any numeric expression and specify the starting point for the array search. If processing a multidimensional array, the usual rules apply to decide which dimension should be used. |
| N |
| Required. Any positive numeric expression giving the number of array elements to use, starting at the element given by the first parameter. If N extends past the upper bound of the lowest array dimension, this computation will "wrap-around" and resume at element 0, until N elements have been processed. |
| Comments: | AValid is not made invalid by invalid array entries. This function is useful in conjunction with the statistical array functions. |
Example:
numValid = AValid(data[0] { Starting element },
100 { Number of elements to search });
The example above finds the number of array elements with valid values, by examining elements 0 to 99.
