The `current-environment-variables' parameter determines the current mutable "environment variable set". If that set is the initial one for a Racket process, then using the set corresponds to working with OS environment variables. Otherwise, it's really just a hash table that is packaged up as OS environment variables if a subprocess is created. The new environment-variable interface works in terms of bytes, instead of assuming that environment variable names and values fit in a string encoding. The string-based `getenv' and `putenv' are still available as convenience wrappers. The checking on environment-variable names for those wrappers is a little tighter, preventing any attempt to use a name that contains "=". |

The Racket Programming Language =============================== Instructions for building Racket from source are in src/README. The main executables in this package: * DrRacket: Racket's integrated development environment (start here!). * racket: command-line tool for running Racket programs. * raco: command-line tool for compilation, documentation, and more. More Information ---------------- For Racket documentation, use DrRacket's `Help' menu, run the `Racket Documentation' application (Windows or Mac OS X), or run `raco docs' from a command line.
