"How do you edit these files?" - Popular editors are reviewed and related to ISPF commands. "What's going on deep down?" - A comparative history describes UNIX and mainframe operating systems and environments. Appendices offer further resources for deciphering common error messages, converting data, comparing hardware, and accessing networks, along with general hints and suggestions for ongoing reading.
