String

String is a Type which may contain characters. String is a synonym for ShortString or AnsiString depending on the current compiler setting.

If Compiler directive {$H} or compiler directive {$LongStrings} is on ( {$H+} or {$LongStrings ON} ), then a String type is the same as an AnsiString type, if not ( {$H-} or {$LongStrings OFF} ), it is a ShortString type.

The ShortString length can be decided by the programmer but is limited to 255 characters. If a ShortString length is not given, the length defaults to 255.

The length of an AnsiString is only limited by available memory.

In the future, there might be a compiler switch to have the String type refer to a Unicode (UTF-8 or UTF-16) String type.
