iteration on VRL records..using HRL’s?

Hi Julie,

I think you have to define a new HRL that’s made up out of a repetition of your VRL. Next you need to get your VRL file as ‘single’ so all VRL records are seen as one message: the HRL.

On iterating the HRL: I would search the archive for that. I’ve already posted some answers on this subject there, like this:

I have made several HRL’s, so I’ll try to explain how I did it.

I have a message, consisting of a header-line and one or more text-lines.

The content of the header is completely different from the text, so I

created a 2 FRL’s: msg_header.frl and msg_text.frl. Every text-line will

start with the string ‘TXT’; this is the segmentname.

Then I created an HRL, which looks like this:

Segment 1

========

Name: header

File name: msg_header.frl

Repeat options: No Repeat

Segment 2

========

Name: text

File name: msg_text.frl

Repeat options: Repeat while

Field: text.segmentname

Value: TXT

It took me a while before I figured out that in the fieldname of the

repeating field, you need to specify

‘.‘ as the field.

Hope this helps!

Hi Julie,

I don’t think it’s impossible what you’re trying to do. But all depends on a correct definition of the HRL.

So I think you first need to make sure your HRL-definition is working correctly. From what you describe, it seems as each line (=record?) is seen as a separate message.

Open the testing tool, click the ‘HRL’ tab. In ‘HRL File’ select your HRL definition and then choose a data file with an example of your HRL to be processed. If this example comes from SMAT, choose ‘Length Encoded’ as format; else choose ‘EOF Terminated’ to make sure the complete file (= all records) is seen as one message.

Then hit ‘Run Command’ to see what the HRL definition makes of your message. This should give an indication on what’s wrong.

Hi Julie,

Did you set your Options | Global Parameters for your VRL?  That’s something I always seem to forget when setting up a VRL for use in an HRL.
