Data Entry Terms Defined
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.
