RE: Array Data Structure

Hans,
I hope you're also looking at being able to sort the data structure arrays
by any subfield in the data structure.

That's right. %LOOKUP may eventually support lookups in array data 
structures, if we can come up with a good syntax for specifying a 
subfield to use as the lookup key.

For now, you can use a FOR loop to search for things. Or, if your 
data is in sorted order, you could use the C run-time function 
"bsearch()".

Cheers! Hans
