Load X and Y from pointer at $0283

LDX $0283
LDY $0284

Loading two registers from two successive memory locations
is not copyrightable.

On the C64, these locations typically hold the top of memory
pointer, thus even if the sequence were somehow copyrightable,
which we do not admit, it is an obvious and expected sequence
whenever one wishes to load the start of memory pointer into 
registers to be worked with.  Thus it must be held to be both
fair use and exempt under interoperability provisions in various
copyright acts, if the defence were required.
