Re: copy one character from a string.

I'm only following advice in Delphi Help <g> ...

"procedure UniqueString(var S: string);

Description
Following a call to SetString, S is guaranteed to reference a unique
string; that is, a string with a reference count of one. For normal
string handling, there is no need to ever call UniqueString. Only in
cases where an application casts a string to a PChar and then modifies
the contents of the string must UniqueString be used."

....or is there something else subtle which UniqueString or SetLength
does ?
