FIX: Memo Field Corruption Occurs with Code Page Differences

ID: Q107520

The information in this article applies to:

  • Microsoft FoxPro for Windows, version 2.5a
  • Microsoft FoxPro for MS-DOS, version 2.5a


When a table is tagged with a code page other than the current working code page, data in a memo field is lost if the memo file is reorganized.

           CREATE TABLE test (xxx m)
           DO SYS(2004)+"\CPZERO" WITH "TEST.DBF",850  && or 1252
           APPEND BLANK
