Perform Varying:- Its a performing of loop using a working
storage variable having a predefined value and its
incremental or decremental value with each execution.
For Example
PERFORM PARA-A VARYING WS-A FROM 1 BY 1.
PERFORM UNTILL:- It is execution of a loop until a certain
condition is met. Please note that condition is checked
before the execution.
PERFORAM PARA-A UNTILL WS-A > 20.
