#### Move; FillChar

GPC supports `Move` and `FillChar`, and they're fully BP compatible. However, some data structures have different internal formats which may become relevant when using these procedures. E.g., using `Move` on file variables does not work in GPC (there are reasons why assigning file variables with `:=` is not allowed in Pascal, and circumventing this restriction with `Move` is not a good idea). For other examples, see String type, Real type, and Endianness assumptions.
