Iterate through list problem

[Elijah Park]

There has been much said on the topic of iteration, but here’s a new one. Hope you’re up for a challenge.

Goal: Iterate through 2 groups of incoming frl fields (diag_1 thru diag_10 then dg2_1 thru dg2_11) placing them in HL7’s 0(0).DG1(1) thru 0(0).DG1(21).

Problem: The first iteration through (list 1 thru 10) works fine. However, when iterating a second time from 1 thru 11 and incrementing the variable by 10, our output gives unexpected results. Help!

Daniel,

Why not set up the FRL fields as repeating and ITERATE as repeating fields rather than trying the brute force list repetition?

Daniel,

In your second iteration, you are using a temp field as the iteration variable on your outbound field (0(0).DG1(@ctr).#3. I don’t believe you can do that, hence the unexpected results.  You’ll need to use an iteration variable (i.e.%l4) and value that in your MATH action instead of @ctr; reference it the same as you do your %l3 variable by using the $ (i.e. $%l4).  Then use that iteration variable in your outbound field path (0(0).DG1(%l4).#3

Hope this helps.

Jim K, sounds like a neat idea…didn’t know you could set an FRL field to repeat.

Jim C, it works like a charm!

Thank you both.

Dan,

It has been a while since I did any ITERATEs over FRL and I thought I simply set up the field names thus:

field_0

field_1

field_2

Then in the Xlate ITERATE selected any one of those fields and Copied to Basis.

I could not find any actual examples of me doing FRL ITERATE so I tried the above in Cloverleaf 5.6 and the basis cannot be set in the manner I recalled.

It is likely my memory is faulty and the method you are using is the method I actually utilized. However I just don’t recall having to know exactly how many occurrences there would be when setting up the ITERATE for FRL (which using a list ITERATE requires).

I think the last time I needed to do something like this was on release 3.3.1 of Cloverleaf.

Sorry if I gave false hope.

NP Jim. I appreciate your feedback.
