Module -> localize names of variables (lexical scoping)
|
|
Block -> localize values of variables (dynamic scoping)
|
|
|
|
Module creates new symbols:
|
|
|
|
Module[{x}, Print[x];
|
|
Module[{x}, Print[x]]
|
|
]
|
|
|
|
->x$119
|
|
->x$120
|
|
|
|
Block localizes values only; it does not create new symbols:
|
|
|
|
x = 7;
|
|
Block[{x=0}, Print[x]]
|
|
Print[x]
|
|
->0
|
|
->7
