as this is 8bit data port with the TRIS set at $00 or $FFCode:glcd_dat var PORTE ' LCD 8 bit data bus
would PBP uses LAT port registers internally ?Code:glcd_tris var TRISE ' Data bus direction

Re: RMW Read modify write
assuming you have lat registers on your pic chip , porte is not equal to late they are separate registers . check the memory map of your chip.
pbp has no glcd native functions, whether your "glcd library" uses late is completely dependent on how the library was written .
if you define your "data bus" as porte I would expect it will not use lat regs (that would probably require two defines , one for each direction)
and lastly rmw has no impact at all when you are writing to the whole port
