I'm trying to get my head across the DT Interrupt code for a small new RC modeling project and I'm trying a test example first (the blinky LED) , compiling with MCS. I have 12f683 selected in MCS and MPASM being used.

but I get an odd warning message from MCS thus :
Warning[219] d:\pbp code\pbp\pbppic14.lib 336 : Invalid RAM location specified
Warning[219] d:\pbp code\pbp\pbppic14.lib 892 : Invalid RAM location specified

Anybody know why and if I should just disregard it ?

I commented out the wsave lines as required (which led me here BTW)

My code

Code:
LED1   VAR  PORTB.1

INCLUDE "DT_INTS-14.bas"     ' Base Interrupt System
INCLUDE "ReEnterPBP.bas"     ' Include if using PBP interrupts

ASM
RBIF = GPIF
RBIE = GPIE

INT_LIST  macro    ; IntSource,        Label,  Type, ResetFlag?
        INT_Handler   TMR1_INT,  _ToggleLED1,   PBP,  yes
    endm
    INT_CREATE               ; Creates the interrupt processor
ENDASM

T1CON = $31                ; Prescaler = 8, TMR1ON
@ INT_ENABLE  TMR1_INT     ; enable Timer 1 interrupts

Main:
  PAUSE 1
GOTO Main

'---[TMR1 - interrupt handler]--------------------------------------------------
ToggleLED1:
     TOGGLE LED1
@ INT_RETURN
My project is quite simple. A 22.5mS interrupt timer (TMR1 I guess) and toggle a few pins then wait for the next interrupt.
