Silvio,

Also there is no need to use macros (&) there, simply do:

USE ( cDbf ) ALIAS ( cAlias ) INDEX ( cDbf ) NEW

Dear Antonio ,
I saw and init carles's sample
i take it as sample base
but now i must use 4 dbfs because  i can explain U : in a one browse i
have the tables of restaurant . the user select one table then the
procedure must open a browse  to insert products (comanda).
but in order the user must select from a dbf a category then the
procedure must open a listbox with products of that category  and the
the procedure must update and insert a product into browse of table of
restaurant .(comanda).
All dbfs  can be on palmar but in future i must link the procedure
with wifi and link this procedure with a pc and i must use the dbf are
in pc (they have cdx and ftp for memo)

I must use 4 dbfs , i need use cdx rdd and i have made a sample test
on forum can you see it and write why it not run?

I not want use tdatabase class (odbf) because i had problems  in past
with the error "alias don't exist"
For xharbour and fwh

Now  from 8 years i use a good method (from my friend Arteaga)

and it run ok , I not had problems with this method but i try to insert
on fwppc language and it make errors .
