Fields on a Form
A field is a space for data entry or display on a form. It usually corresponds to a column in a database table, but also can be used for other purposes in an application, such as displaying instructions or the results of computations, or for entry of user names and passwords.
There are two kinds of fields:
Simple fields--Data is displayed one item at a time.
Table fields--Multiple rows and columns of data are displayed simultaneously.
If you create a form for a table, you choose one of these formats. On forms associated with JoinDefs, the JoinDef specification determines which data is displayed in simple fields and which is displayed in table fields.
Both simple fields and table fields consist of an internal name, data window, attributes, and an optional title, as described in the following sections.
