Perhaps I found a solution

nNumero := eval(oDbf:fieldWBlock(cField ))

I must only read it

   local cField   := "NAME"

   oDbf  := TDataBase():Open( nil, "STATES.DBF", "DBFCDX", .T. )
   ? oDbf:FieldGet( cField ), oDbf:&cField

How to write a right name of a field

Since you are already using a database object, instead of this:

oDbf:FieldGet( cField )
oDbf:FieldPut( cField, <newvalue> )

You can just do:

oDBF:ID
oDBF:Name

Where ID and NAME are fieldnames. Then you can do:

msgInfo( oDBF:ID )

To put data into a field of a database object you just do:

oDBF:ID := cID
oDBF:Name := cName

However you should always use a meaningful name for the database object, so it should be something like:

oCustomer:ID
oCustomer:Name

You should not use oDBF as an object name because all that tells you is that it is a database object, but not which database object. And, obviously you can't have multiple database objects open in the same routine all with the same name, like "oDBF." But you can have something like oCustomer and oInvoice open in the same routine since there is no name conflict.

Using these conventions makes your code very easy to read and understand, even years after you wrote it.
