I have a below piece of code in my SKELETON that is used in CLIST. It is a inline COBOL code;

)BLANK
IF (WS-DUP12 >> '00' AND << '14')
THEN MOVE '01' TO WS-DDR
ELSE IF (WS-DUP12 >> '13' AND << '24')
THEN MOVE '02' TO WS-DDR
)BLANK

Can anyone explain about the operators << and >> and how it behaves in this case!

why don't you take a look at a COBOL reference manaul
and see if these operators are legal?

what happens when You run the ispf dialog and You look at the file tailoring result

the answer is there icon_cool.gif

the problem/topic is not cobol related, moved where it belongs
see

I guess that my SKELETON is inappropriate if You had written it You should know why >> and << were used..
let' say that You got the short end of the stick ....
