I havent tracked this discussion, but its just possible that you may
have missed the significance of H+ (if using D3+). If the compiler
option is H-, then string == shortstring. If it is H+ then
string==ansistring. If using D3+, you should never use string as the
type, always qualify it as shortstring or ansistring. Note that
string[8] is automatically shortstring.
The compiler has a serious bug, which will kick in if you are using
string for type definition. Theoretically the compiler does auto
conversions etc between the two string types. It fails however when
the declaration is in another unit.
For example, unit A defines
{$h-}
var
AString : string
Every reference to AString in unitA is as a shortstring. Which is
fine. Now enters unit B.
{$h+}
var
BString : string;
BString is an ansistring. But because AString was defined in unit A,
its definition as visible to unit B is "string". Because unit B has
h+, it treats AString as an ansistring. Any interaction between
AString and BString is doomed to failure. This normally manifests
itself as missing characters in the string.
Whats worse are function/procedure definitions, especially from 3rd
part libraries where the beggars have been lazy and used string to
define things. Anyone with any clout, please kick some backsides -
starting with Borland, Infopower, Turbopower ......
