DSTB The instruction will use a short form if the B register is used as the destination register. SRCA The instruction will use a short form if the A register is used as the source register. SRCB The instruction will use a short form if the B register is used as the source register. A.2.4 Apostrophes The apostrophes in the syntax field are a notation used for the parser generator and are not put in the assembler source statement. - 9 - A.3 Notes A.3.1 Reserved_Symbols A.3.1.1 Machine_Dependent_Reserved_Symbols A B ST a b st A.3.1.2 Standard_Reserved_Symbols AND DEFINED EQ GE GT HIGH LE LOW LT MOD NE NOT OR SHL SHR XOR and defined eq ge gt high le low lt mod ne not or shl shr xor CONTENTS A.
