File is already created but I can not get the program to compile. Current
iteration of the program looks like this. I am creating the variable length
field in the D Spec since I can not do it in the KFLD line. Then in the
EVAL line I am moving a fixed length field OHPRON into the field and then I
try to access the file. Error *RNF7055 is displayed below.


D W#TRAK 20A VARYING
*
C S1KEY KLIST
C KFLD OHCONO
C KFLD OHCSNO
C KFLD W#TRAK
*
C eval w#trak = ohpron
*RNF7055 C s1key setll shipments1
C read shipments1 34


*RNF7055 30 Factor 1 S1KEY is not valid for the specified operation.

CREATE INDEX LIBRARY/INDEXNAME ON LIBRARY/FILENAME (
FIELD1 ASC,
FIELD2 ASC,
FIELD3 ASC)
WITH 3 DISTINCT VALUES

You should be able to use the CREATE INDEX to build an index over the
table.

The file was created via SQL from a Windows SQL Server onto the iSeries.

You using DDS or SQL?

DDS: use the VARLEN keyword on the field.

SQL: define the field as VARCHAR.

Ok,

So you've got bad data in the file, 'ABC '
instead of just
'ABC'.

My recommendation: fix the data and prevent it from being
put in wrong!
;-)

Still, a quick test doesn't show me what the issue is. 'ABC' is
ordered
before 'ABC '

If you do a SETLL, with 'ABC', don't you still see both records?

Or are you trying to CHAIN with 'ABC' and the file has 'ABC
' (or
vice versa)?

Hm, that would be a problem......

The only thing I could think of, would be to either chain with both
values
or do a SETLL and a couple
of reads.

BUT, the reality is, 'ABC' and 'ABC ' are
different. You could
have both records in the
system, you can't consider them the same and expect only
one or the other.

I repeat: fix the data and prevent it from being put in wrong! ;-)


HTH,
Charles

The only issue I have had in accessing files with variable length
fields is making sure the trailing blanks have been
trimmed. A 20
byte fixed
length field is 'ABC '. The 20 byte
variable length
field is normally 'ABC'.

How does one go about accessing file that one of the key
fields is a
variable length field in ILE RPG? I have to add such a
file to an
existing program. Only thing I could think of was with Embedded
SQL.
Is there any other way or is Embedded SQL the only way?
