%trim searches from both ends of the string to find the non-blank data.
If the string is long and the data is short, repeated trimming can
involve a lot of searching.

To eliminate most of your trims -and- make your code nicer, consider
using varying length fields, or at least varying length temporaries.
When using varying fields, you normally only have to do at most one trim
to get trimmed data into the field in the first place.
