The following statement results in the creation of both a variable named NEXT_APP and a 10-element array named APP_LIST. Both the variable and each element of the array have the form of the structure APPOINTMENT.
RECORD /APPOINTMENT/ NEXT_APP,APP_LIST(10)
The following examples show aggregate and scalar field references.
NEXT_APP ! The record NEXT_APP NEXT_APP.APP_TIME(1) ! An array field of the variable ! NEXT_APP APP_LIST(3).APP_DATE ! A 4-byte array field in the record array ! APP_LIST(3)
NEXT_APP.APP_FLAG ! A LOGICAL field of the record ! NEXT_APP
! The first character of APP_MEMO(1),
! a character*20 field of the record
Fields within a record can be accessed collectively or
individually. Record references are either qualified or
A qualified reference refers to a typed data item and can be used wherever an ordinary variable is allowed. Type conversion rules are the same as for variables. Its form is:
Unqualified references refer to a record structure or substructure and can be used (in most cases) like arrays.
rname The name used in the RECORD statement to identify a record.
cfname A substructure field name within the record identified by record-name.
afname The name of a typed data item within a structure declaration.
