The 2nd Question(It has no relationship with the first question.)

Choice 1 05 ORDER-DATE PIC S9(9) PACKED-DECIMAL VALUE 20000204.

hi frnd,
Can u explain clearly about this:
For the order file described above, where must ORD-DATE be reformatted to include the correct century so it can be sorted in ascending sequence using an internal sort?
actually what u mean for.. either sorting by year or by anything else
and since binary values are more easy for the sytem to manipulate or to perform i had said choice 3 for the second question. check it. |

I think what you explain is right.
The 2nd question, I know binary values are more efficient when manipulate, but just now I am wondering whether it need to manipulate when SORT. I think you are right.
Thanks khamarutheen. |
