1) Since the data cannot be accessed from other functions, data integrity is preserved. 2) Only required data can be passed to function, thus protecting the remaining data.

Its not that the compiler can't initialize local variables; its that the compiler does not initialize local variables.This is by design and language specification. If you want to initialize local variables, you must explicitly do so.
Global variables can be seen in all blocks of your program, when local variables are visible only within the block where it's declared.
Auto variables are stored on the stack alongside all other local variables.
Only global/static variables are, local variables aren't.
Faster execution of code.
1. Local variables cannot be used by other forms. 2. Cannot be used globally. 3. They can slowdown the compiling process.

Local Variables There are two types of variables based on the location of declaration 1. Instance Variables- Declared inside a class, but outside of any method's body. 2. Local Variables- Declared inside a method's body inside a class.
In FoxPro, there are three types of memory variables: local variables, private variables, and public variables. Local variables are defined within a specific procedure or function and are only accessible there. Private variables are available throughout the current program but not in called procedures. Public variables can be accessed from anywhere in the application, making them globally available.
