FT_AEMINLEN()
 Find shortest element within an array
──────────────────────────────────────────────────────────────────────────────

 Syntax

      FT_AEMINLEN( <aArray> [, <nDimension> [, <nStart> [, <nCount> ] ] ] )
                 -> nMinlen

 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 shortest size element of an array.

 Description

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

 Examples

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

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

     FT_AEMINLEN(aArray,2,,9)  // Measure Elements 1-9 of 2nd dimension

     FT_AEMINLEN(aArray,3,5,9) // Measure Elements 5-9 of 3rd dimension

     FT_AEMINLEN(aArray,3,5)   // Measure Elements 5 to end of 3rd dimension
