Further to Tore's SQL solution, you could have written:

REPLACE ALL CHAR18 WITH "3" for CHAR8="ÌäæÈ ÚãÇä                                         "
REPLACE ALL  CHAR18 WITH "8" for CHAR8="ãÍÇÝÙÉ ÇÑÈÏ                                       "
REPLACE ALL  CHAR18 WITH "2" for CHAR8="ÛÑÈ ÚãÇä                                          "

Pleas note also that your originalcode should not have worked because you need to move the file pointer after a "Set Filter", ususally by "Go Top", before you do you table searches, updates. etc. on the filtered data.
