SMLofNJ implements a subset of the structure of the same name provided in Standard ML of New Jersey. It is included to make it easier to port programs between the two systems. The semantics of these functions may be different than in SML/NJ.

- structure Cont

  implements continuations.

- SysInfo.getHostArch ()

  returns the string for the architecture.

- SysInfo.getOSKind

  returns the OS kind.

- SysInfo.getOSName ()

  returns the string for the host.

- exnHistory

  the same as MLton.Exn.history.

- getCmdName ()

  the same as CommandLine.name ().

- getArgs ()

  the same as CommandLine.arguments ().

- getAllArgs ()

  the same as getCmdName()::getArgs().

- exportFn f

  saves the state of the computation to a file that will apply f to the command-line arguments upon restart.

- exportML f

  saves the state of the computation to file f and continue. Returns true in the restarted computation and false in the continuing computation.
