That's right, but you're using it wrong.  The difference between creating=
 a=20
constant (using EQU) and an address for a variable (using EQU) is *nothin=
g*=20
--- at least for the declaration.  However, there is a difference based o=
n=20
how *you* decide to use it.  If you decide that you want to use it as a=20
constant, then just use it as such, eg: "movlw  temp".  If you know that =
it's=20
a variable, then you'll only use in it statements such as "movwf  temp".

Yeah, it's confusing at first, but if you adopt a system of notation (any=
=20
system you choose), then it'll be easier to read.  I use all uppercase fo=
r=20
constants, and first-letter-upper otherwise.  All lowercase is for the=20
reserved words.

Stop. Read this paragraph later...
Once you get comfortable with this, then add to your confusion by reading=
 the=20
sections on indirect addressing.  Here, you'll declare a variable name, b=
ut=20
use it as a constant to move the address of that variable into a register=
,=20
etc, etc.
