Alan,

If you know you only have three columns change the innermost loop to:

for i = 1 to 3
   ? oRow.Columns(i).Value
endfor

You can also stop the row iteration when you find the first blank row, otherwise it'll process every possible row in the spreadsheet.

if ( empty( oRow.Columns(1).Value ) )
   exit
endif

>How can I limit the number of columns that are processed. It looks like it is processing over a hundred columns for each row. In reality I only need the first three.
