Description

The LABEL() function is used to return the description of the field <expN> in the currently selected table. Fields are numbered from 1 to FLDCOUNT() according to their position in the table structure.

If <expN> exceeds the number of fields in the table, or there is no currently selected table, then LABEL() returns a null string.

Example

close databases
clear
open database southwind
use example
for i = 1 to fldcount()
    ? "Field: " + field(i) + " - Description: " + label(i)
next
