binding

A one-to-one correspondence between entities in two domains. The association between an identifier and its resource (a location in memory) is called a binding. In 4GL, the correspondence between form fields and program variables during data entry is also called a binding. Several 4GL user interaction statements include a binding clause that lists the names of accept user input from a form field and program variables and their corresponding form fields (or database columns). These statements include CONSTRUCT, INPUT, INPUT ARRAY, and PROMPT.
