All TM (test-under-mask) instructions should use BO/BOR/BNO/BNOR/BM/BMR branch instructions rather than BZ/BZR/BNZ/BNZR branch instructions. The USING instruction specifies a base address and range and assigns one or more base registers. If you also load the base register with the base address, This topic contains reference articles for the operating system assembler instruction set.

Assembler instructions. An assembler instruction is a request to the assembler to do certain operations during the assembly of a source module; for example, defining data constants Assembler language is made up of statements that represent either instructions or comments. The instruction statements are the working part of the language, and At assembly time, the assembler converts the symbolic assembler language representation of the machine instructions to the corresponding object code.
