Guys thanks for the Help,
I figured the problem
In simple words, XREAD read 80 bytes as maximum, input record, from in-stream data or DD as a CHAR.
So, Using XDEIC will convert first number from input record, CHAR to Binary ,and to get the second number from the input record, 80 bytes that has been read, we use
AND TO READ the third number of the the input record, XDEIC r,0(,1) again
continue with this till the end of the input record.
The numbers in r are a binary and you can use them for math operation
To convert the number back to decimal use XDECO
So, following these steps I got the correct answers
I consider this issue has been solved
