Up: Conventions for Binary Tables
Previous: Arrays of Strings
The original binary table proposal, the A3DTABLE extension,
introduced the concept of a table entry or field of more than one
element, a vector. It provided this structure through the use of a
repeat count. However, since an array of more than one dimension can be
reduced to a one-dimensional vector, as occurs when arrays are stored in
a computer, the repeat count can be used to define multidimensional
arrays as well. To do so, conventions are needed to specify how such an
array is organized in the table field.
