If you are working with a default form, VIFRED automatically places a field on the form for every data column in the associated table or JoinDef and creates the appropriate link between the field and its data column.

If you prefer to create your own simple fields, you can do so with the Create Field operation. However, the only way you can link such a user‑created field to a data column in a table is to write application code that links the field's internal name to a data column in the table. If you are not familiar with this type of programming, we recommend that you work with default forms created from JoinDefs or tables, rather than creating your own fields.
