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.

Thank you for your reply

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
