Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named in honour of the French mathematician, philosopher and physicist Blaise Pascal.

Lexical Analysis is the first phase of the compiler also known as a scanner. It converts the High level input program into a sequence of Tokens.

To Generate Tokens and symbol table from file in inputs folder:

`python main.py ./inputs/source_code.pas`

Two Output files will be generated :

`outputs/pascal_tokens.csv`
`outputs/symbol_table.csv`
