Imagine it:
Scenario: Temp.Dbf Struct is {{"NField", "N", 10, 0} } and 1000 records
FUNCTION Main
Local aNewStruct:= {{"NField", "N", 3, 0}}
// This generates run time error data width error
dbModStruct("Temp.Dbf", aNewStruct)
RETURN NIL

dbcreate(D_APP,ADBF) // Create nes dbf with new structure
use
use &(D_APP) alias APPOGGIO && open it
append from &(D_FDBF) // append data
use
Now rename
