Answer / sujit kumar biswal.
Witout key u can use either SETGT or SETLL.And witought key
these two opcodes work only folloing conditions.
1.U can spesify any sequence no in factor1

We can read the records from the file directly without any
key field.
*LOVAL SETLL XXXX

Put it in the DO loop and check for the EOF.

The question is how you retrieve records from externally
defined files without using a key.
You can do this by designating the file as a primary file in
the program.
