  Here is an example of what i want to do
  
  

  ' {$STAMP BS2px}
  ' {$PBASIC 2.5}
   
  value   VAR     Word
  Value1  VAR     value
  value2  VAR     Word
  value3  VAR     value2
   
  addr    VAR     Word                       ' EEPROM address
  test    VAR     Byte                       ' test byte read back
   
   
  Main:
  
  DO
  
    value  = $1010
    value2 = $2003
    PUT 0,Word value, Word value2             ' write value to SP location 0
                                              ' and value2 to SP locations 1 & 2
   
    value  = $FF                              ' modify variables
    value2 = $FFFF
   
    GET 0,Word value, Word value2             ' retrieve from Scratchpad
   
    DEBUG HEX4 ? value                        ' display
    DEBUG HEX4 ? value2
  
    PAUSE 2000
  
    value1 = $1111
    value3 = $222
  
    PUT 1,Word value, Word value2             ' write value to SP location 0
                                              '  and value2 to SP locations 1 & 2
   
   
    value1 = $FF                               ' modify variables
    value3 = $FFFF
   
    GET 1,Word value1, Word value3             ' retrieve from Scratchpad
   
    DEBUG HEX4 ? value1                        ' display
    DEBUG HEX4 ? value3
   
    LOOP

  I believe the "scratch-pad" RAM is Static Ram. Thus it does not suffer the 'wear-out' effect of eeprom. But it also doesn't hold its data when power cycles on and off.

  That fine if it dose not hold data when the power is removed
