I don't mean to sound like a broken record, but why are you setting your 
data bits AFTER raising E1?? Your code:


> wrte
>       call       BusyFlag
>       bsf                   RS
>       bcf                   RW
>       bsf                   E1
> 
>       movf     daten
>       movwf   PORTB
> 
>       bcf                   E1
> 
>       return


Wouldn't it make more sense to use:


wrte
         call    BusyFlag

         movf    daten
         movwf   PORTB

         bsf     RS
         bcf     RW

         bsf     E1
         bcf     E1

         return


Thereby putting your output on PORTB before clocking E1...
