I've found an issue when using the @@symbol with a pointer list.
You need to be aware when your pointers need to be WORD or LONG offsets.
The compiler seems to switch from expecting WORD lists to LONG lists.
The example below shows reading WORDs as LONGS and then flips?
Changing to LONG pointers fixes the problem.
The compiler needs to check overflow of the WORD pointers and possibly warn of the switch over to expecting LONG lists.
The SPIN2 docs show WORD examples only.
