Node: String schema, Next: Strings in variant records, Up: Strings in GPC

#### What's this confusion about strings?

Turbo Pascal strings have a length byte in front. Since a byte has the range 0 .. 255, this limits a string to 255 characters. However, the Pascal string schema, as defined in section 6.4.3.3.3 of the ISO 10206 Extended Pascal standard, is a schema record:

         type
           String (Capacity: Integer) = record
             Length: 0 .. Capacity;
             String: packed array [1 .. Capacity + 1] of Char
           end;

The `+ 1` is a GPC extension to make it feasible to automatically add the `#0` terminator when passing or assigning them to CStrings. Thus at the expense of a little added complexity (must declare capacity, don't use `GetMem` without explicit initialization of the `Capacity` field, and the additional space requirement) you can now have very long strings.
