title: How to REDEFINE and perform arithmetic on a PIC X clause in COBOL
body: <p>I need to move a PIC X defined field that has numerics with a 2 position decimal to a numeric field to perform an arithmatic function involving a comp-3 field. What is the best way to do this?</p>
  
  <p>I did do a redefine from the PIC X to a PIC 9 with the following:
  EX. PIC X(10) to PIC 9(7).99.</p>
  
  <p>But now how do I perform a computation with that redefined field? Do I redefine the redefined field?</p>
  
  <p>Compute FIELD-RESULT defined as S9(9)v99 = FIELD-1 (defined as S9(9)V99) - FIELD-2(my redefined field PIC 9(7).99.</p>
  
  <p>Thanks!!</p>
