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
C READP RECORDFORMATNAME/PROG.NAME
C FIELDNAME1 DSPLY
C FIELDNAME DSPLY
C ENDDO

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.

Answer / syam
Yes, You can retrieve records from External Physical File
with key.
1.Specify PF as a program described file in RPG Program.
FFilNam IF F 80 6AIDISK KEYLOC(7)
(80=Record Lenght, 6=Key Lenght, (7)=Key starting
position)
2. IFilNam KD 01 1 C0 2 C1
I 7 12 NAME
(KD=Sequence,01=Record Id,1&2=Starting position,C=Any
Character,0=Value. Means In my file each record is having 1
and 2 posion = 01 to identify record, 7 to 12 =Name)
3.C MOVE 'SYAM' NAME
C 'SYAM' CHAIN FilNam
C N41 MOVEL NAME CUSNME
