===== ARRAY MANAGEMENT BOUNDS =====

==== PURPOSE ====
 This small example will show how to retrieve the bounds of arrays.  

==== SOURCE CODE ====
   
   DIM number(5,4,3)
   
   PRINT "UBOUND(number) should be 5: "; UBOUND(number)
   PRINT "UBOUND(number,0) should be 5: "; UBOUND(number,0)
   PRINT "UBOUND(number,2) should be 3: "; UBOUND(number,2)
