Hi,
When I use copy on a PChar (e.g. copy(p,1,1)), it is very slow,
because the compiler converts the PChar to a string.
Is there already a function for PChar?
Can an overloaded version of copy be added?

Not sure why it is allowed in the first place. If out of Delphi compatibility, maybe we should leave
it enabled for {$mode delphi}

I don't know about an already existing such function (well, actually SetString used to work that way
in the past, but no longer), but here's

Thanks. But apparently I was not exact enough.
Copy has the nice feature, that the bounds are checked.
For PChar it does that too, but it always runs through the whole PChar
