 Find longest element within an array
──────────────────────────────────────────────────────────────────────────────

 Syntax

      FT_AEMAXLEN( <aArray> [, <nDimension> [, <nStart> [, <nCount> ] ] ] ) ;
                 -> nMaxlen

 Arguments

     <aArray> is the array containing the elements to be measured.

     <nDimension> is the array dimension to be measured,
                defaults to first dimension.

     <nStart> is the starting array element to include,
                defaults to first array element.

     <nCount> is the number of array elements to process from
                from <nStart>, defaults to remaining elements
                in array.

 Returns

     The length of the longest size element of an array.

 Description

     This function will measure each element of an array
     dimension and return the longest element.

 Examples

     FT_AEMAXLEN(aArray)       // Measure the 1st dimension of an Array

     FT_AEMAXLEN(aArray,2)     // Measure the 2nd dimension of an Array

     FT_AEMAXLEN(aArray,2,,9)  // Measure Elements 1-9 of the
                                     2nd dimension or subarray

     FT_AEMAXLEN(aArray,3,5,9) // Measure Elements 5-9 of the
                                     3rd dimension or subarray

     FT_AEMAXLEN(aArray,3,5)   // Measure Elements 5 to last in the
                                     3rd dimension or subarray
