Variable-Length Fields

Variable-length fields store only the actual data in the field, and not the trailing spaces that would be added for a fixed-length field.

Variable-length fields should be defined after any fixed-length fields in the entity. Each entity should have at least one fixed length field that can be used as the primary key. A variable length field cannot be used as a key.

A variable length field has VC (or VU in older applications) or W field definition.

When defining more than one variable-length field, define a string identifier for the field, which enables Uniface to keep track of the beginning and end of the field.
