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
2.Also *hival is work with it.
3.Field name work but only for intiger.
so code ur programe as answer4,but just change the *loval
to any sequence no or *hival then readp or any int field
one ex.
F PF/LFNAME IF E DISK
C *HIVAL SETLL RECORDFORMATNAME/PROG.NAME
C DOW %EOF

Answer / gk
We can read the records from the file directly without any
key field.
*LOVAL SETLL XXXX
READ XXXX
Put it in the DO loop and check for the EOF.
Hope you have got the answer.

Answer / ld123q44
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.
