The construction of first compiler for the language FORTAN (formula translator) around 1956 was whose success was not at all assured. It was figured among the largest programming projects of the time. A Compiler is a black-box program which takes source code written in some highlevel programming language and compiles it into the language that computer can understand and execute. This process is done through a number of stages. Starting with the recognition of the token through the target code generation provide a basic for communication interface between a user and a processor in a significant amount of time. It is basically a simple programming language that helps in solving different functions and modules of programming in a very simple manner. More of a programming language is difficult to understand and time consuming in terms of compilation. ProgramNepal helps in breaking the bar of conventional programming language. It is dynamically typed language because it is associated with run-time values. Due to this programmer can write a little quicker because we do not have to specified types every time.0
