Paul, your code started as following:
>porta   equ     5
>
>start
>        clrf    0                       ; Make sure RAM page bits are 0
>        movlw   3
>        option
>        movlw   10                      ; Port A.0 as output
>        tris    porta
PortA,0 has to be tris'ed as output
PortA,1 has to be tris'Ed as input
Your problem probably is that you had an other number radix in mind at your
movlw-instructions than mpasm decodes. So better explicitely add the radix:
        movlw    d'3'                   ; decimal 3
        option
        movlw    b'11111110'            ; binary, bit0=output, other bits=input
        tris     porta
