title: How to move number in Text to number?
body: <p>I would like to ask, how to move number in Text, e.g: 01 A   PIC X(6) value "200030", to a number such as 01 B  PIC 9(6) and I only want to extract the first 4 number of A. In Cobol this type of move using MOVE is forbidden, the move I used is MOVE A(1:4) to B.</p>
