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?
