Assembly language to object program

How does an assembler program create object code?

An assembler program creates object code by translating combinations of mnemonics and syntax for operations and addressing modes into their numerical equivalents. This representation typically includes
An operation code ("opcode") as well as other control bits and data.

What is assembly code?

Assembly code is plain-text and (somewhat) human read-able source code that mostly has a direct 1:1 analog with machine instructions. This is accomplished using mnemonics for the actual instructions
Registers
Or other resources. Examples includeJMP and MULT for the CPU's jump and multiplication instructions.

What is the difference between opcode and assembler?

Some bits are for opcode and some are for operands. Assembly language is converted into executable machine code by a utility program referred to as an assembler; the conversion process is referred to as assembly
Or assembling the code.

How do assemblers run a machine language program?

The assembler accepts a source program as input, checks for format errors, and produces an object module containing the machine language program. A loader then loads the object module into the memory of the target machine. There the machine language program is run, possibly with the aid of a debugger.

How do I learn assembly code?

Learn the representation of assembly code that is used inside the Universal Forward Translator (it’s a superset of virtual object code). Design your own concrete syntax for the assembly language. Unparse internal representations into your concrete syntax. Start learning to program with monads: an error monad and a parsing monad. Why am I doing it?
