(defgroup iron-main ()
"A minor mode to edit files and interact with IBM MVS or z/OS .
This is a minor mode just because it is a good thing to have a
shared location where to centralize definitions for the main modes
and functionalities that make up this package. E.g., see the major
modes `jcl-mode' and `asmibm-mode'."
:group 'languages)
(defcustom iron-main-os-flavor "MVS 3.8j"
"The current flavor of MVS used.
The values of this variable are strings starting either with 'MVS' or
'z/OS'. Other variants are acceptable as long as the 'main' OS name
comes first.
The value \"MVS 3.8j\" is the default one, being the version of MVS
that IBM released in the public domain."
:group 'iron-main
:type 'string)
(defcustom iron-main-machine "Hercules 4.x"
"The machine IRON MAIN connects to.
The default is \"Hercules\", meaning the Hercules emulator. Another
possible values is \"IBM machine\", in which case we mean real heavy
iron hardware.
The values for this variable are strings starting with the type of
machine to which a 'connection' can be made. For the time being the
only meaningful value is a string starting with 'Hercules', intended
as a variant of the Hercules emulator. In the future it may be
possible to have also strings starting with 'IBM' (or, possibly,
'Hitachi', etc.).
If this variable has a 'Hercules' value, the Hercules emulator is
running and it has the internal HTTP server active, then IRON MAIN
will be able to extract some information about it.
If the Hercules emulator is running and it has the 'card reader'
active on port 3505 (or another suitable one), then it is possible for
IRON MAIN to at least submit jobs to it, especially if it has a
version of 'MVS' (or 'z/OS') running."
:group 'iron-main
:type 'string)
(defgroup iron-main-hercules ()
"The IRON MAIN subgroup for local Hercules customization."
:group 'iron-main)

"Hercules")
"SDL/Hyperion 4.3.x")

;; Hardcoded FTTB; make it more intelligent later.

"The host Hercules uses to listen for HTTP requests."

"The more or less standard port Hercules uses to listen for HTTP requests."

"The folder where the OS running on Hercules resides..
This variable makes sense only for Hercules installations, i.e., for
setups where the value of `iron-main-machine' is \"Hercules ...\"."
:group 'iron-main-hercules

(defcustom iron-main-hercules-dasd-dir "dasd"

setups where the value of `iron-main-machine' is \"Hercules ...\"."
:group 'iron-main-hercules
:type 'string

(defcustom iron-main-hercules-card-reader-port 3505
"The port where the Hercules 'card reader' listens to.
Hercules usually has a 'card reader' configured to listen on a socket
with default port number 3505 (the IBM card reader devide model
number). This reader, if configured, can be used submit JCL directly,
which is what IRON MAIN exploits in `jcl-mode'."
