Assembler Primer Tutorial
Assembler programming is a very early form of software code, dating back as far as 1954, that sits, in the spectrum of computer language sophistication, between computer machine code and the compiled source codes of modern programming languages (which comparatively read like a story … good luck with Assembler stories … gobbleLITTLELESSgook?!), predating BASIC and FORTRAN. The Wikipedia page about compilers puts this in historical perspective “
The first compiler was written by Grace Hopper, in 1952, for the A-0 programming language. The FORTRAN team led by John Backus at IBM is generally credited as having introduced the first complete compiler in 1957.
” Let’s see some information about Assembler, from Wikipedia, below.
An assembly language is a low-level programming language for a computer, or other programmable device, in which there is a very strong (generally one-to-one) correspondence between the language and the architecture’s machine code instructions. Each assembly language is specific to a particular computer architecture, in contrast to most high-level programming languages, which are generally portable across multiple architectures, but require interpreters or compiling.
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.
Assembly language uses a mnemonic to represent each low-level machine operation or opcode. Some opcodes require one or more operands as part of the instruction, and most assemblers can take labels and symbols as operands to represent addresses and constants, instead of hard coding them into the program. Macro assemblers include a macroinstruction facility so that assembly language text can be pre-assigned to a name, and that name can be used to insert the text into other code. Many assemblers offer additional mechanisms to facilitate program development, to control the assembly process, and to aid debugging.
The tutorial shows some simple Assembler code in action for a Hello World program after seeing some slides regarding the install of MASM 32bit compiler of Assembler code. Please take care if you go ahead installing MASM 32bit Assembler compiler, and, as mentioned several times with the install, do not proceed if there are even warning messages from the install, or, pretty obviously, if you do not have 32bit Windows as your operating system.
