' Notes *************************************************************************
' Ubound function finds the maximum number of the array in this case it is 100.
' The reason i used this is because the project I am working on has arrays that
' vary in length. For more information MS Visual Basic help
'
' The program is very simple.  To find the maximum or minimum value set the first
' value of the array as maximum or minimum.  The program goes through the array
' from 1 to 100 (Ubound).  If the value is greater then the set maximum value then
' The value is set as that value.  If the next value is lower than the set value
' Then the program carries on the next value in the array.  The reverse is true for
' for the minimum.  If the value is lower then that is the new value
