record | type |
Syntax | A recordType is:
| ||||||||||||||||||||||||||||||||||||
Description | Each value of a record type consists of fields, one field for each name (id) declared inside the record. In the following example, the fields are name, phoneNumber and address.
| ||||||||||||||||||||||||||||||||||||
Example |
type phoneRecord : record name : string ( 20 ) phoneNumber : int address : string ( 50 ) end record … var oneEntry : phoneRecord var phoneBook : array 1 .. 100 of phoneRecord var i : int oneEntry .name := "Turing, Alan" … phoneBook ( i ) := oneEntry % Assign whole record | ||||||||||||||||||||||||||||||||||||
Details | In a record, id's of fields must be distinct. However, these need not be distinct from identifiers outside the record. Records can be assigned as a whole (to records of an equivalent type), but they cannot be compared. A semicolon can optionally follow each typeSpec. Any array contained in a record must have bounds that are known at compile time. The notation > can be used to access record fields. For example, if p is a pointer to phoneRecord, p>name locates the name field. See pointer.
