Hi,

I am believing that you have Idea about c/java. I can explain in that way.

Example of a function in C/Java

int add( int a, int b ) {
         int sum;
         sum = a +  b;
         return  sum;
     }

So if you observe the above function ; it is expecting a and b values(Parameters of mentioned  function). and inside the function there is another variable which is sum.

If we compare same thing with pega ; a and b variables are like parameters (created for reusability by passing values dynamically). And sum is like Local variable. The scope of that variable is up to that function (Local to that function). In pega  the scope of local variable is up to the rule. It will be useful for manipulations within the steps of the rule. There is no scope for local variables after out of the rule.
