Global Variables are the variables that are used anywhere
in the project. These can be called or used across the
process or sub process that is with in the project.
Global variables can be overridden at runtime.

There are 3 types of variables
1) Global Variables-----through out the project ( used for
constants)

2) Process variables-----Activities in the project where
the variables are defined.

3) Shared Variables ------ Across multiple process instances
( used to share data)

Answer / keshini vyas

global variables are created by defining them outside of all the functions including the main in the program. The common practice is that all global variables are defined at the begining of the program code before any function. global variables can be accessed from any function including main function and other user defined functions.

example
int x,y; /* Global Variable*/
main()
{
int a,b;/*local variable*/
statement 1;
statement 2;
.
.
.
statement n;
}

Answer / poornima

can add/edit the Global variables using Global Variable
Editor.
