WHY is MPLAB V8/7 treating label assignments as if they generated code?

I have an old project that assembled and ran just fine in MPLAB V5.x,
but V5 doesn't support the Pickit3 or ICD3 I now have to work with.
(And now in Win7 so V5 won't install either).

MPLAB V8. and V7 barf up copious errors if I attempt to use the code as=20
is, in absolute mode.

I moved the code to MPLAB V8.7x (as new project) and I cannot seem to=20
get the assembler to properly handle my numerous 'equ' and 'res'=20
assignments correctly.
I have to have absolute assignments because of existing boot loader=20
linkages to specific RAM locations (and it's all one blob of code).

I get " Overwriting previous address contents 0x20 ... " for any=20
subsequent CODE that is generated for 0x20 to 0x1ff (the RAM/REGISTER=20
range).
I use the ORG directive to put labels where I need them to be.

It is as if MPASM sees the label assignment I have for the RAM=20
registers, and ASSUMES that code was generated at that address, even=20
though none actually IS generated.

How do I get MPLAB V8 to behave 'properly'. eg. NOT see a label=20
assignment as having created code at that same address?

I have searched for many hours now, and have turned up nothing relevant.

Help??
Thanks in advance. I has to be something incredibly simple I am missing.

  for this filler macro.

000C   29             01468     fill (goto Rstjmp),0xFE-$ ;trap errant=20
code in page 0

which writes a jump vector into all unused code space in page 0 in order=20
to trap and reset any errant operation.

The same errors happen for code any generated at 0x100 0x1ff ONLY where=20
I have defines for RAM using the same addresses. e.g. buffer start=20
addresses or arrays.
