FLDCOUNT()
 Evaluates the number of fields in a database file.
 Returns <expN> number of fields in the currently selected database file.

 Useful in initializing arrays from database files where each element
 is a field.

 * Assumes open file, appropriate record, clear screen
 max_fields = FLDCOUNT()
 DECLARE array[ max_fields ]

 FOR i = 1 TO max_fields  && load field data into array
    m_field = FIELD(i)
    array[i] = &m_field
 NEXT

 FOR i = 1 TO max_fields  && paint the screen
    @ i, 0 SAY FIELDNAME(i) GET array[i]
 NEXT

 DO WHILE .T.  && does user want to edit, save, or cancel?
    @ 23, 5 SAY "Press <E> to edit, <S> to save, "+;
                "or any other key to cancel changes..."
    choice = INKEY(5000)
    @ 23, 5    && clear the user prompt
