Data Typing

The issue of defining the data part was discussed at length. There was agreement towards a small and simple data definition language, including built-ins. The latter must be defined in the language and here special syntactic/semantic treatment needed for conciseness and readability. Some points that emerged are:

• Built-ins to include: booleans, bits, integers, enumeration, characters.

• Built-in composed types: records, arrays, lists, character strings.

• Partially defined functions. A majority consensus is that partial functions, and applications of functions must be treated in .

• It is considered to be very desirable that a clear interface mechanism towards other languages be defined, e.g. towards ASN.1, IDL, SDL.
