Shree,

1.What are the ways to find out the tables used in the program?

You will have to debug and find out.

2.what is the difference between select single * and select up to 1 rows??

Single will rely on the key you speicfy and get the first record it counters. UP TO 1 row, will fetch all the rows and give you one.

3.

Since internal tables have fixed line structures, they are not suited to handle data sets with varying structures. Instead, you can use extract datasets for this purpose.

An extract is a sequential dataset in the memory area of the program. You can only address the entries in the dataset within a special loop.

Regards,

Ravi
