AEVAL()

Evaluated the subscript element of an array

Syntax

AEVAL(<aArray>, <bBlock>, [<nStart>], [<nCount>]) --> aArray

Arguments

<aArray> Is the array to be evaluated.

<bBlock> Is a code block to evaluate for each element processed.

<nStart> The beginning array element to evaluate.

<nCount> The number of elements to process.

Returns

<aArray> an array pointer reference.

Description

This function will evaluate and process the subscript elements in <aArray>. A code block passed as <bBlock> defines the operation to be executed on each element of the array. All elements in <aArray> will be evaluated unless specified by a beginning subscript position in <nStart> for <nCount> elements.

Two parameters are passed to the code block <bBlock>. The individual elements in an array are the first parameter and the subscript position is the second.

AEVAL() does not replace a FOR...NEXT loop for processing arrays. If an array is an autonomous unit, AEVAL() is appropriate. If the array is to be altered or if elements are to be reevaluated, a FOR...NEXT loop is more appropriate.
