AValid

Description: This function returns the number of valid elements in an array sub-range.

Returns: Numeric

Usage: Script or Steady State

Format: AValid(ArrayElem, N)

Parameters: ArrayElem { array element } { required } { no default: }

An array element. The subscript(s) for the array may be any numeric expression and specify the starting point for the array search. If not specified, the lowest dimension of a multidimensional array is used.

N { numeric } { required } { no default: }

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.
