Vectors

If the row you are editing represents a column which is a variable length vector, tick the Variable check box. The Vector properties appear, these give the size of the vector in one of two ways:

• Link Field Reference. The name of a column containing the number of elements in the variable length vector. This should have an integer or float type, and have its Is Link field property set.
• Vector prefix. Specifies 1-, 2-, or 4-byte prefix containing the number of elements in the vector.

If the row you are editing represents a column which is a vector of known length, enter the number of elements in the Vector Occurs box.
