 292                 Array index out of range
------------------------------------------------------------------------------
 Description
   This error occurs when the code attempted to index an array element that
   is out of bounds for the particular array.

   Arrays in Force are 0 based, a feature identical to the C language,
   but different from Clipper (where arrays are 1-based). The most common
   reason for an out-of-bound error to occur is to declare an array with a
   given number of elements, then access the element of the array which is
   indexed with the same number, as demonstrated in the code fragment below.

   vardef
      uint aNumbers[ 10 ] // array with 10 elements
   enddef
   aNumbers[ 0 ]  := 1    // access the first element with index number 0
   aNumbers[ 9 ]  := 10   // access the last element with index number 9
   aNumbers[ 10 ] := 11   // attempt to access the 11st element, which
                          // does not exist

   The Force compiler encodes array range checking by default. Out-of-bounds
   errors are a result of this service. Checking arrays can be disabled
   by using the -Ga compiler switch, in which case accessing the wrong
   elements in arrays will result in more or less obvious program bugs.

 Solution
   Only access the valid range of array elements.
