The sample programs rely on the Standard ML Basis Library.
Starting with Chapter 7, they also rely (to a minor extent) on recent changes to ML itself. I am distributing the code in a form suitable for up-to-date ML compilers, alongside versions of the programs for chapters 3, 8 and 10 for use with older compilers.Older compilers (pre-1998) might be incompatible in three respects:
Complicating matters further, in 2004 the ML Basis Library was modified slightly. Compilers compliant with the changes reject a few of the functions presented in the book. To address this issue, post-2004 versions of the code for chapters 8 and 9 are provided.
Later chapters sometimes refer to code presented in earlier chapters. However, if you compile the code for all the chapters in order, there should be no compilation errors.
