FUNCTION AppendFromDelimited
TPARAMETERS tcFile as string, toFor as System::Delegate, ;
 taListFields() as string, tcCharDelimiter as string, ;
tcFieldDelimiter as string, tnCodePage as Integer

perhaps enhancing tcCharDelimiter from vfp's CHAR to string is helpful, as that might enable something like
append from () delimited with ", " && ","+Space(1)
and thereby making the next pass replacing all but the first field with the LTRIM() unneeded...
