Syntax
DSE Id ExternalFileName
Description
This instruction defines a data structure external to the prototype, by means of a database file.
Important note: The system verifies the existence of the external file.
The name is the guide word of an alphanumeric variable or a code which does not exceed 6 characters.
In the latter case, the DSE is defined as a variable, which should be defined with the *NODEF reference field.
Restrictions
In a DSE defined by Adelia, you must not use the dummy properties of the corresponding file, because they will not be generated.
