        bcf     nResultByte, bResultBit ; assume result bit is zero
        movf    nTemp,W
        andlw   (1<<3 + 1<<4 + 1<< 5)   ; w := 00xyz0000
        btfss   STATUS,Z
        bsf     nResultByte, bResultBit ; sets result bit

I think this should do it.
If all the bits 3, 4 and 5 are zero, W := z,
the zero flag is set and the result bit is not
