Load and with

Question

Anybody can explain the difference between load and with functions?

1. You can define multiple local variable either Inside load() or with() but you can't perform save operation over the variables which 
are defined inside with() whereas we can save the data into a variable which is defined inside load() 
 
2. Variables defined in load() instantiate for only once whereas variables defined in with() will be evaluated for each interaction 
on form, like sort, search, input a value in field etc. However forcefully you can dynamically change the value of the variables defined on load() as well. 
 
3. Performance wise load() is faster than with() because of only once execution. 
 
4. Any consistent values should be maintained in the variables defined in load() where as maintain those variables in 
 with() which are expected to change its value based on given input.

load(): While loading the page, local variables value are assigned/mapped. This mapping happens only once. local variables associated with load are the used for storing the value if any internal calculation needed. with(): This function differs from the load() function because it recalculates the local variable values after every user interaction with the interface. A local variable may be defined with or without a value, and the value may be simple or complex. When a value is not defined, it's assigned a null value.

Load() 
->Define local variables within an expression for a SAIL interface and evaluate the expression with local variables. 
->Retrieve data sets once and not have to get multiple times in an expression. 
->We can also used to create variables that capturing same data just like any other variable on a form. However, these variables only store data for a length the user is looking and interacting with a screen. When the user freshers or leaves screen the data in the local variables deleted. 
With() 
->Define local variables within a function and evaluate the expression with the new variables. 
->It recalculates the local variable values each time the expression is reevaluated. 
->The expression defined in load and with functions can also contain the other variables such as rule inputs and process variables etc., 
 ex:- load(local!a:1,local!a+rule!b) which returns 2(assuming the rule!b value as 1).
