Simple if inside the logic block it is local variable.
If outside the logic block it is global variable.
logic block means the block which is in between '{' and '}'.

If variable is declared globally, then it should be declared like X 40.

Variable is said to be a local if it is used in a block in which it is declared.
It's scope is end if the block is end.
Whereas global is visible to all blocks of a program.
As it is not declared inside any block.
It's scope is end if the block is end.
Whereas global is visible to all blocks of a program.
As it is not declared inside any block.
