The ?ASSIGN command can be entered at any time prior to running a query. Each time
an ?ASSIGN command is entered, an entry of the assignment is made in the internal
table. The internal table holds up to 32 assignments. When the internal table is full, the
?ASSIGN command can be entered without any parameters to clear all of the
assignments.
Each DDL dictionary RECORD statement describes records in a physical file, named by
a DDL FILE IS clause. Enform Plus uses the physical file name in the DDL FILE IS
clause to locate the records and retrieve information. The actual records desired are not
always in the physical file named in the dictionary. An example would be when test
records are used in place of actual records. The ?ASSIGN command temporarily
overrides the physical file named by the DDL FILE IS clause. In the following
example, the employee record description is assigned to the physical file
$data.database.sample:
?ASSIGN employee TO $data.database.sample
