**pointwise data entry**

An input box for each data point in a data set:

This sort of data entry is generally limited to 99 data points. Blank boxes are ignored.

**bulk data entry**

One input box for all data points in a data set:

This sort of data entry is generally limited to 1024 data points. Individual data-points are separated by spaces, commas, tabs, or newlines. If you have the data available on a different screen, you should be able to copy and paste it into the bulk data box. The above two data input examples are transmitted as identical data-sets.
