Is self-loading array possible?

[K1200]

I have a table where each record contains an editable value (along with associated information). At runtime, I need access to the values as a one-dimensional array, so I transfer them at startup into a global repeating field. All this works fine, but I got to thinking:

Is there a way to define an unstored calculated repeating field that effectively resolves its contents in realtime, whenever another calculation references the field? I put together a test file using text fields in place of numbers (easier to see what's happening). I've tried a couple of different approaches but all I've been able to get is a value in the array's first position. What I need is for the second record's value to be in the second position and the third record's in the third position and so on. I don't necessarily expect the array to be fully populated all the time (e.g., for display), but when referenced from another calculation (Alpha::Result in the example file), it needs to return the proper record's value.

Is it even possible to do this, or should I leave well enough alone and stay with my original approach? (BTW, there are 200 records in the table, so I really don't want to use a 200-element case statement, which seems very inefficient if it's even possible.)

Thanks in advance for any suggestions.

Hi

try this

Excellent!

I tried it in my application and it works like a charm. I had not had a reason to use the Extend function before and (based on the book definition) I'm afraid I would not have thought to try it for this.

This is an elegant solution that provides a displayable array as well.

Thank you very much.
