Yes, It's possible according to ANSI - 85 standards only if both the variables declared in 01 Level.

Hi Narendra,

Redefines is mainly for utilizing memory space.

A PIC X
B REDIFINES A PIC XX.

MOVE 1 TO A.
DISPLAY B.

Now B will contain 1b. ( b for space).

Any corrections welcome.

hello priya,

in ANSI 74 we can redefine one variable into any other variable with same length(we can not increase or decrease the size).but in ANSI 85 standard we can decrease the size but we can not increase(you can read boo).i am working in Z/OS .in that i am trying to increase the size its working perfectely.but in OS/390 (in real time) it can not work.in faq's they told increase is possible.but is not possible.i attend one interview in that interview i face this question but i told it possible that time the interviewer told me it is not possible.
corrections are welcome.............
thanks®ards,
