Thanks Steve - and others who also replied!

It's late here, and seeing 'dex' in Boisy's Liber809 blog had me really 
confused because I couldn't find it in any instruction set listings... and 
then it tweaked when I saw the opcode was $30... and confirmed when it was 
listed under '6800 compatibility instructions' - doh!
