Hi friends,

What is Set & Let where we use Set & Let?

Hi,

with SET you just can assign a value, with LET you can make a calculation and assign the outupt.

SET varS=1+1; // varS = '1+1'

LET varL=1+1; // varL = 2

In addition to SebastianLettner see here The Magic of Variables for more details and explanations.

SET simply assigns what is after the equal to operator whereas let evaluates what is after the equal to operator.

Example:

2*2

Using SET the result will be 2*2

Using LET the result will be 4

Thanks

Set:

set variables are used define to define paths,strings etc

SET variable name =string;

it can be only used in script

and with Set only assign the value .

LET:

Let evaluates the expression

it can be created through script/UI.

Let variable name=Expression

It can be used in Chart calculations passing values inside the expression.
