Description

The FIELDNAME() function is synonymous with the FIELD() function. It returns the name of the field <expN> in the table currently selected. The optional <workarea | alias> parameter can be used to operate on the table in the specified workarea number, or with the specified table alias. If the optional <expN3> is specified and evaluates to 1, the field data type initial (e.g. 'C' for character), the field width and the field value will also be returned along with the fieldname in a comma separated string.

If <expN1> exceeds the number of fields in the table, or there is no currently selected table, then FIELDNAME() returns a null string. Field offsets start at 1. The FIELDNAME() function always returns a character string in upper case.
