HEADER([nWorkArea | cTableAlias])


nWorkArea| cTableAlias

Returns the header size for a table open in another work area. nWorkArea specifies the work area number and cTableAlias specifies the table alias. If you omit the work area and alias, HEADER(В ) returns the size of the header for the table open in the current work area. HEADER(В ) returns 0 if a table isn't open in the work area you specify. If a table doesn't have the alias you specify, Visual FoxPro displays an error message.

Return Value



A table header contains information about the table itself, such as the field names and sizes and the presence of a memo file or structural index.
