In Algol, Pascal, Miranda, and Explanation : Dynamic scoping creates variables that can be called from outside the block of code in which they are defined. I know this won't make much sense but let me explain this with the help of an example. Dynamic Scope Once defined, every part of your program can access a variable.

Find centralized, trusted content and collaborate around the technologies you use most. are patent descriptions/images in public domain? With dynamic scoping, we have a stack of variable definitions tracked at runtime -- so which x we write to depends on what exactly is in scope and has been defined dynamically at runtime. Static scoping or lexical scoping means that where a variable is declared can be determined by looking in the surrounding scopes. In a pure functional language (like Haskell) variables cannot change their value. From my understanding, the result of this program when run using static scoping is: x=13, y=7, and z=2.
