Description

The FIELDINFO() function is used to return a string containing comma-separated information about a specified field <expN1> in the currently selected table or the workarea/cursor numbered <expN2>. Fields are numbered from 1 to FLDCOUNT() according to their position in the table structure.

If <expN1> exceeds the number of fields in the table, or there is no currently selected table or no table open in workarea <expN2>, then FIELDINFO() returns a null string.

Otherwise, the information string is structured as follows:

#	Value
1	Field name
2	Field type
3	Field width
4	Field decimals
5	Field description
6	Field default value
7	Field picture value
8	Field choices value
9	Field validation expression
10	Field validation error text
11	Field help/tooltip text
12	Field mandatory ("1" if True)
13	Field autoinc ("1" if True)
