RE: Lookup on MODS -- RPG400-L

We're on V5R4 and data structure arrays can be used - just not some of the new features of data structure arrays. If you search on Midrange.com there is a thread about using %lookup. Answer: it needs V6R1 or better. I have searched twice now, the second time I found the answer to me from the first time. :>)

The answer I found best for V5R4 was here:

Ricky,

Yes, but . . .

Which means you may want to consider changing your legacy Multiple Occurance DS to a Data Structure Array

Do a web search for "Those Weird and Wonderful Arrays", an MC Press article by Paul Tuohy.

Also look at SORTA and $SUBARR in the ILE RPG Language Reference 7.1

So, there is the potential problem of your current release level because what I suggest depends on recent releases.

If you are current on release, data structure arrays, the new Overlay data specification, and the other improvements like BASED(basing_pointer_name) has made flexible data sorting much easier.

I am working on a program using all of these techniques as I type this.

Subject: Lookup on MODS

Trying to figure out is there is a way to find a specific occurance of a
MODS? I need to be able to LOOKUP the occurance where Seq = 2 for example
but it might be in Occurance 3. The only thing I can think of is to read through the MODS and create another array field with the Seq number with the Index being the Occurance. Is there a better way?

d DetailDS ds Occurs(52)

d Seq Like(SEQ# )

d FromDate Like(FROMDT )

d ToDate Like(TODT )
