Hi,

I want to overwrite a binary value in my file through overlay on a particular condition.



apart from this I want to overwrite a binary field with 200 at a position 380 on same above mentioned condition .

Can anybody help me in this ?

Hi ,

We can do in this way :



hex value of 200 - 00C8.

Yes, that will work. FYI, here's another way to do it with DFSORT that doesn't require knowing that 200 = X'00C8'.

Thanks Frank its working !

Just want to know how binary values will be stored internally and is there any way we can see how they are stored like we can see hex values .

richagoyal,

Read this FI format positive/negative number and BI for positive number

Your question doesn't make a lot of sense - hex IS a representation of the bits that are stored.

So when we show +200 as hex 00C4, that is how it is stored internally - in bit representation that would be:
0000000011000100

But we normally use hex to represent the bits rather than 1s and 0s.
