Key fifo

[longpole001]

Hi guys , i having some trouble getting my head arround doing a fifo for keys , what i need is FIFO which goes upto 5 deep ,

so as progressively 5 keys are pressed , the array builds down , and the newest key is Key_array(0) , oldest is Key_array(4) , if key_value = 10 then clear the values from array

  if key >0  then 
  
   for Key_count  = 4 to 1 step - 1 
       Key_value(Key_count) = Key_value( Key_count - 1)
   next Key_count     
 
    Key_Value(0) = Key
   endif

this seems to work
