SUMMARY
=======

This article shows by example how to search for duplicate character strings by
using macro substitution to examine each field of each record. When found, the
duplicate character string, the field name containing the string, and the
corresponding record number are displayed on the FoxPro desktop. This code can
be modified to search for as many character strings as needed.

Step-by-Step Example
--------------------

1. Create a free table called Names that contains six fields of Character type
  with a width of 10. Name the fields field1, field2, field3, field4, field5,
  and field6.

2. Load 10 records. Populate some fields with the name SMITH and the rest with
  names of your choice. Make certain that in some records SMITH appears in more
  than one field.

3. Create a program and insert the following code:

     CLOSE DATABASES
     CLEAR
     USE names
     SCAN                            && Search through each record
       FOR i = 1 TO FCOUNT()         &&Search through each field
           x = FIELD(i)              && Assign the field name to a variable
           IF UPPER(&;x) = "SMITH"
             ? &x + "   " + FIELD(i) + "   " + "Record # " ;
                + LTRIM(STR(RECNO()))
           ENDIF                     && Insert needed IF ENDIF statements
           NEXT i
       ENDFOR
     ENDSCAN

4. Run the program, and notice that the information that is displayed on the
  FoxPro desktop.
