I was using MEMORY VARIABLES, but now i´m trying to use BUFFERING MODE and i need use the ALLTRIM function. My sintax is GRUPOS.COD_GRU=ALLTRIM(GRUPOS.COD_GRU) And the Visual Fox show me a message saying OBJECT GRUPOS IS NOT FOUND. What i´m doing wrong Thanks Anderson Reis Girardi Athenas Automação e Sistemas Porto Alegre-RS/Brazil ander@net1.com.br
