Hi Julie,
Is you inbound data coming in as a file containing similar records except for the last field? Your proc looks like it would expect an EOF terminated file format. If this is true, your proc is probably a good way to go. If you are concerned with setting a correct field size, you could always add a check in your proc to kick out an error if max number of recs are received.
You may also want to define multiple subfields in your VRL to hold the concatenated numbers. This would allow you to utilize the built in xlate functions such as iterate. Your subfields would look like:
your_field35_name.[0]
your_field35_name.[1]
your_field35_name.[2]
Your xlate could then iter through the subfields.
Hope this helps.
