where is storageReg located? iirc mpasm defaults to access bank operations (which don't require setting of the BSR but only allow access to the first 128 bytes of memory and the special function registers) when you don't specify the thirc parameter. (and yes this is the opposite of what the pics datasheet says)

movff otoh allows direct access to stuff in any bank without having to use the BSR.
