SASM is a programming language made in C++ inspired by the basic ASM. The goal is to give an example to students of a little programming language (parser). I am not using a compiler !
WARNING: The language is like an emulator, it's not saved in your real memory ! By the way, in the reality every instruction are in the memory.
There is a lot of definitions of special objects like Registers, Memory, etc. It's like you're defining a type of word or sentence.
The lexer is the first part of an interpreted language, his role is to create the grammar of the language.
The parser use the results of the lexer to create something, like if you were saying a sentence, you have verbs, adjectives, adverbs etc. and you use them to create a sentence.
The files with the name "Expecter" are used to obtain the desired arguments, in this language we can wait for a value, a register or an instruction.
