HERCULES(1) User Commands HERCULES(1) NAME Hercules - IBM System/370, ESA/390, and z/Architecture Emulator SYNOPSIS hercules [-f config-filename] [-d] [-b logo-filename] [-p dyn-load-dir] [[-l dynmod-to-load]...] [> logfile] DESCRIPTION Hercules is a software implementation of the System/370, ESA/390 and z/Architecture mainframe architectures. It means that your PC can emulate an IBM mainframe processor. The main- frame can range from a System/360 to a z10 - running in "S/370" mode, "ESA/390" mode, or "z/Architecture" mode. Hercules executes S/370, ESA/390, and z/Architecture instructions and channel programs. It emulates mainframe I/O devices by using PC de- vices. For example, 3390 DASD devices are emulated by large files on your hard disk, and local 3270 screens are emulated by tn3270 sessions. (Note: Not all 370 and 390 features have been implemented in Hercules. Also, certain non-standard models, 360/20s, and the 360/67 virtual mem- ory mode are not emulated.) Hercules implements only the raw S/370, ESA/390, and z/Architecture in- struction set; it does not provide any operating system facilities. This means that you need to provide an operating system or standalone program which Hercules can load from an emulated disk or tape device. You will have to write the operating system or standalone program your- self, unless you can manage to obtain a license from IBM to run one of their operating systems on your PC, or use IBM programs and operating systems which have been placed in the public domain. OPTIONS -f config-filename Sets the name of the configuration file. The default, if none is specified, is hercules.cnf. The default may be overridden via the HERCULES_CNF environment variable. -d Specifies that Hercules is to be run in 'daemon' mode, wherein it runs invisibly with no attached console. -b logo-filename Sets the name of the file containg the screen logo that's pre- sented when a 3270 terminal connects. When not specified the de- fault herclogo.txt file is looked for and when not found the built-in logo is used. -p dyn-load-dir Sets the directory from which dynamic modules are to be loaded. The default depends on the host platform on which Hercules is being run. This option overrides the default. -l dynmod-to-load Sets the name of an additional dynamic module to be loaded at startup. More than one additional module may be specified, al- though each must be preceded with the -l option specifier. logfile Sets an optional log file which will receive a copy of all mes- sages displayed on the control panel FILES hercules.cnf ENVIRONMENT HERCULES_CNF AUTHORS Hercules was created by Roger Bowler. Jay Maynard (the Tron Guy) was the maintainer from 2000 to 2012. Jan Jaeger designed and implemented many of the advanced features of Hercules, including dynamic reconfigu- ration, integrated console, interpretive execution and z/Architecture support. A dedicated crew of programmers is constantly at work imple- menting new features and fixing bugs. This manual page was written by Dan Hork using text snippets from the Hercules web site.
