5. Hercules Supplied Utilities
5.1 Overview
Several utility programs exist to support the Hercules Emulator. Most of them are used when working with
DASD and TAPE files. Other utilities perform some special functions with configuration files.
All these utility programs are pure line-command mode programs (i.e. Windows DOS or Unix/Linux shell).
They can be called manually from the command line prompt or built into batch files. This is generally the
preferred method due to its greater flexibility and automation possibilities.
If the Hercules GUI (HercGUI) is used the utilities can also be called interactively via the GUI and using a
graphical and menu driven interface.
