In C, and maybe assembly, a better phrase is the following:

        if (020H != Buffer)
        error "headspace error: uncomment the movlw line!"
        endif

That is, the constant is on the *left* hand side of a comparison.  If you
slip, and write:

        if (020H = Buffer)

you'll get the the appropriate error from your compiler.  Compilers are
tools -- use the wisely to catch the ugliest problems for you.

I've spent way too many hours tracing down why "if (i=0)" never works...
