4 Scheme Interoperability

Using the conversion rules in Libraries and Collections, and R⁶RS library can refer to modules that are implemented in other dialects supported by PLT Scheme, and other PLT Scheme modules can refer to libraries that are implemented in R⁶RS.

Beware that a pair in R⁶RS corresponds to a mutable pair in scheme/base. Otherwise, R⁶RS libraries and scheme/base share the same datatype for numbers, characters, strings, bytevectors (a.k.a. byte strings), vectors, and so on. Hash tables are different. Input and output ports from scheme/base can be used directly as binary ports with R⁶RS libraries, and all R⁶RS ports can be used as ports in scheme/base programs, but only textual ports created via R⁶RS libraries can be used by other R⁶RS operations that expect textual ports.
