Delphi uses integer conventions similar to C, although the names are case-insensitive, as with BASIC. That is, a Delphi INTEGER value may be either a PowerBASIC INTEGER or LONG, depending on whether the Delphi code is 16-bit or 32-bit.
The elements of multi-dimensional arrays, in Delphi, are not necessarily stored in a straightforward order in memory. Such arrays are not compatible with other languages.
