'CLB' is CLear Borrow and assembles the same as 'SEC'. 'SBB' is SuBtract with Borrow and assembles the same as 'SBC'. 'BNB' is Branch Not Borrow and assembles the same as 'BCS'. 'BB' is Branch Borrow and assembles the same as 'BCC'. > PS how can you change mnemonics from within Merlin8? If Merlin8 has macro capability then these op codes could be defined as macros. Willi
