My MPLAB 7.01 installation is as following. There is nothing
wrong with it. Maybe you need to check your installation.

> Hello everyone,
> According to the linker script that comes with MPLAB 
> ver7.01(16f870.lkr or 16f870i.lkr) all the
> RAMs are unbanked. There's no DATABANK sections in the 
> script, only SHAREBANK.
> According to the datasheet that's not the case, there are two 
> blocks of general purpose
> registers (0x20 to 0x7F and 0xA0 to 0xBF) which are indeed banked. 
> The included with MPLAB template f870tempo.asm won't even 
> compile properly with the
> supplied script.
> Any ideas why is it so, any particular reason?
> Best regards
> VV
