Frederick,
To add to what Tracy said...
You can change the codepage on a table using the cpzero program; you should find it if you do a search on your C drive. Copy that program somewhere in your VFP path, so it will be available when you need it. Codepage 437 should work for FPW 2.6. You can call it like this, on a table that is not currently open.
cpzero("mytable.dbf",437)
>I've been using some FPW 2.6 tables in VFP 6.0, adding records, deleting, packing, reindex, etc... Haven't added any new fields. Am running across compatiblity problems of "Not a Fox table/DBF" when trying to USE the table in FPW 2.6.
