variables having two types they are set and let 

set: set variables having static values like fixed values

ex: set v1= 30 or set v2='qlikview'

let: let variables having calculated values and also static values.

ex: let v3= 30+40 or let v4= 'qliksence'

the main thing is let is static and let is dinamic.

set :--

it assigns the variable without evaluates the expression ex- set v1=3+4
o/p--3+4

let :-- it assingns the variable with evaluates the ecpressin

ex:-- let v2=3+4 o/p --7

SET or a LET statement is often used To define the variable. The SET statement is used when you want a variable to hold the string or numeric value that is to the right of the Equal (=) sign.

The LET statement is used when you need to evaluate what is to the right of the Equal sign

e.g

set myVar=52 the result is “52″

Let myVar=5*2 the result is “10″
