 AIns() 
 Inserts an element into an array.  
 Syntax 
 AIns( <aArray>, <nElement>, [<xValue>], [<lGrow>] ) --> aArray 
  
 Arguments 
 <aArray>  
 A variable holding the array to insert an element into.  
 <nElement>  
 This is a numeric expression indicating the ordinal position where to insert the new array element. It must be in the range between 1 and Len(<aArray>).  
 <xValue>  
 A value of arbitrary data type to assign to the new array element. It defaults to NIL.  
 <lGrow>  
 Optionally, a logical value can be specified. If .T. (true) is passed, the length of the array is enlarged by one element. The default value is .F. (false) leaving the number of elements in <aArray> unchanged.
