CBI Datatypes.
Unlike many languages, the CBI control language doesn't rely on
general purpose datatypes. Instead it provides a collection of
specifically targetted datatypes. This allows the compiler to
validate all entered values for range and type before a schedule
runs. This is important in a language that is designed for unattended
operation of a telescope. The builtin datatypes are listed under the
heading CBI Datatypes in the contents
page.
Users can also define aggregates of the builtin datatypes to form group datatypes.
Many of the CBI datatypes are derived from more general datatype
classes. All datatypes of a given class understand the same syntax and
expressions, but they differ in the range of values that they
allow. For further details, see the section on datatype classes or follow the links from the
index below.
