Thanks. This is sort-of too verbose when use. I have no comments about how to define it, but when use it, can we just use:
ProcessArray(someintarray); ? The complier should be able to "specialize" it implicitly because it knows someintarray is array of integer? alternatively, how about this: var proc_ints: specialize ProcessArray<LongInt>; begin proc_ints(someintarray); end; use it without explicit specialize is best, however. 2013/9/4 Sven Barth <pascaldra...@googlemail.com> > Am 04.09.2013 08:18, schrieb Xiangrong Fang: > > Hi There, > > I try to write a procedure with generic parameters, but failed: > > type > generic TArray<T> = array of T; > > procedure ProcessArray(arr: TArray<T>); > begin > end; > > > The compiler said "Generics without specialization cannot be used..." > > But if I specialize the parameter then this procedure is useless. > > Any ideas? > > This is not yet supported.
