DT Instant Interrupts - Clarification?

[Aussie Barry]

Hmmm.... it would appear that DT_INST-14 doesn't work with PIC12F683
I downloaded Ver 1.1 of the application and trialed the "Hello World" program from Darrel's website.
I made the necessary change from PORTB.1 to GPIO.1 for the LED1 variable but got a host of errors when compiling:

Error[101] DT_INTS-14 TEST.ASM 235 : ERROR: (wsave variable not found,)
Error[101] DT_INTS-14 TEST.ASM 201 : ERROR: (" Add:" wsave VAR BYTE $20 SYSTEM)
Error[101] DT_INTS-14 TEST.ASM 256 : ERROR: (Chip has RAM in BANK1, but wsave1 was not found.)
Error[101] DT_INTS-14 TEST.ASM 208 : ERROR: (" Add:" wsave1 VAR BYTE $A0 SYSTEM)


Should I be able to do this with a PIC12F683?
Can anyone provide some input to this problem?

I have attached a copy of the full code for review.

Cheers
