Added support to find dlopen in either libdl or libdld since some platforms package it there.
VAX/11 730 VAX/11 750 VAX 8600/8650 MicroVAX I MicroVAX II rtVAX 1000 (or Industrial VAX 620)
RQ has new disk types: RC25, RCF25, RA80
RQ device has a settable controller type (RQDX3, UDA50, KLESI, RUX50)
RQ disks default to Autosize without regard to disk type
RQ disks on PDP11 can have RAUSER size beyond 2GB
DMC11 DDCMP DECnet device simulation from Rob Jarratt. Up to 4 DMC11 devices are supported.
DZ on Unibus systems can have up to 256 ports (default of 32), on
Qbus systems 128 port limit (default of 16).
DZ devices optionally support full modem control (and port speed settings
when connected to serial ports).
DHU11 (device VH) on Unibus systems now has 16 ports per multiplexer.
MicroVAX 3900 and MicroVAX II have SET CPU AUTOBOOT option
MicroVAX 3900 has a SET CPU MODEL=(MicroVAX|VAXServer) command to change between system types
Added support for TCP connections using IPv4 and/or IPv6.
Logging - Traffic going out individual lines can be optionally logged to
files
Buffering - Traffic going to a multiplexor (or Console) line can
optionally be buffered while a telnet session is not connected
and the buffered contents will be sent out a newly connecting
telnet session. This allows a user to review what may have
happened before they connect to that session.
Serial Port support based on work by J David Bryan and Holger Veit
Serial Console Support
Separate TCP listening ports per line
Outgoing connections per line (virtual Null Modem cable).
* Disk and Tape I/O can be asynchronous. Asynchronous support exists for pdp11_rq, pdp11_rp and pdp11_tq devices (used by VAX and PDP11 simulators). * Multiplexer I/O (Telnet and/or Serial) can be asynchronous. Asynchronous support exists for console I/O and most multiplexer devices. (Still experimental - not currently by default)
RAW Disk Access (including CDROM) Virtual Disk Container files, including differincing disks
Simulators which have boot commands which load constant files as part of booting have those files imbedded into the simulator executable. The imbedded files are used if the normal boot file isn't found when the simulator boots. Specific examples are: VAX (MicroVAX 3900 - ka655x.bin), VAX8600 (VAX 8600 - vmb.exe), VAX780 (VAX 11/780 - vmb.exe), VAX750 (VAX 11/750 - vmb.exe), VAX730 (VAX 11/730 - vmb.exe), VAX610 (MicroVAX I - ka610.bin), VAX620 (rtVAX 1000 - ka620.bin), VAX630 (MicroVAX II - ka630.bin)
The following extensions to the SCP command language without affecting prior behavior:
GOTO <Label> Command is now available. Labels are lines
in which the first non whitespace character
is a :. The target of a goto is the first
matching label in the current do command
file which is encountered. Since labels
dont do anything else besides being the
targets of gotos, they could be used to
provide comments in do command files, for
example (:: This is a comment)
SET ON Enables error trapping for currently defined
traps (by ON commands)
SET NOON Disables error trapping for currently
defined traps (by ON commands)
RETURN Return from the current do command file
execution with the status from the last
executed command
RETURN <statusvalue> Return from the current do command file
execution with the indicated status. Status
can be a number or a SCPE_<conditionname>
name string.
ON <statusvalue> commandtoprocess{; additionalcommandtoprocess}
Sets the action(s) to take when the specific
error status is returned by a command in the
currently running do command file. Multiple
actions can be specified with each delimited
by a semicolon character (just like
breakpoint action commands).
ON ERROR commandtoprocess{; additionalcommandtoprocess}
Sets the default action(s) to take when any
otherwise unspecified error status is returned
by a command in the currently running do
command file. Multiple actions can be
specified with each delimited by a semicolon
character (just like breakpoint action
commands).
ON <statusvalue>
ON ERROR Clears the default actions to take when any
otherwise unspecified error status is
returned by a command in the currently
running do command file.
Error traps can be taken for any command which returns a status other than SCPE_STEP, SCPE_OK, and SCPE_EXIT.
ON Traps can specify any status value from the following list: NXM, UNATT, IOERR, CSUM, FMT, NOATT, OPENERR, MEM, ARG, STEP, UNK, RO, INCOMP, STOP, TTIERR, TTOERR, EOF, REL, NOPARAM, ALATT, TIMER, SIGERR, TTYERR, SUB, NOFNC, UDIS, NORO, INVSW, MISVAL, 2FARG, 2MARG, NXDEV, NXUN, NXREG, NXPAR, NEST, IERR, MTRLNT, LOST, TTMO, STALL, AFAIL. These values can be indicated by name or by their internal numeric value (not recommended).
Interactions with ASSERT command and DO e: DO e is equivalent to SET ON, which by itself it equivalent to SET ON; ON ERROR RETURN. ASSERT failure have several different actions: If error trapping is not enabled then AFAIL causes exit from the current do command file. If error trapping is enabled and an explicit ON AFAIL action is defined, then the specified action is performed. If error trapping is enabled and no ON AFAIL action is defined, then an AFAIL causes exit from the current do command file.
Other related changes/extensions: The ! command (execute a command on the local OS), now returns the commands exit status as the status from the ! command. This allows ON conditions to handle error status responses from OS commands and act as desired.

Built In variables %DATE%, %TIME%, %CTIME%, %STATUS%, %TSTATUS%, %SIM_VERIFY%, %SIM_QUIET%, %SIM_MESSAGE% Command Aliases
Token “%0” expands to the command file name. Token %n (n being a single digit) expands to the n'th argument Tonen %* expands to the whole set of arguments (%1 ... %9)
The input sequence “%” represents a literal “%”, and “\” represents a literal "". All other character combinations are rendered literally.
Omitted parameters result in null-string substitutions.
A Tokens preceeded and followed by % characters are expanded as environment variables, and if one isn't found then can be one of several special variables:
%DATE% yyyy/mm/dd
%TIME% hh:mm:ss
%CTIME% Www Mmm dd hh:mm:ss yyyy
%STATUS% Status value from the last command executed
%TSTATUS% The text form of the last status value
%SIM_VERIFY% The Verify/Verbose mode of the current Do command file
%SIM_VERBOSE% The Verify/Verbose mode of the current Do command file
%SIM_QUIET% The Quiet mode of the current Do command file
%SIM_MESSAGE% The message display status of the current Do command file
Environment variable lookups are done first with the precise name between the % characters and if that fails, then the name between the % characters is upcased and a lookup of that valus is attempted.
The first Space delimited token on the line is extracted in uppercase and then looked up as an environment variable. If found it the value is supstituted for the original string before expanding everything else. If it is not found, then the original beginning token on the line is left untouched.
commands can be aliases with environment variables. For example:
sim> set env say=echo sim> say Hello there Hello there
The SHIFT command will shift the %1 thru %9 arguments to the left one position.
Simulators for the Windows platform are built and made available on a regular basis (at least once a week if changes have been made to the codebase).
The prebuilt Windows binaries will run on all versions of Microsoft Windows from Windows XP onward.
They can be accessed at https://github.com/simh/simh-Win32-Download
Several relatively recent versions should be available which you can download and use directly.
First download the latest source code from the github repository's master branch at https://github.com/simh/simh/archive/master.zip
Depending on your host platform one of the following steps should be followed:
If you are interested in using a simulator with Ethernet networking support (i.e. one of the VAX simulators or the PDP11), then you should make sure you have the correct networking components available. The instructions in https://github.com/simh/simh/blob/master/0readme_ethernet.txt describe the required steps to get ethernet networking components installed and how to configure your environment.
See the 0readme_ethernet.txt file for details about the required network components for your platform. Once your operating system has the correct networking components available the following command will build working simulators:
$ make {simulator-name (i.e. vax)}
Compiling on windows is supported with recent versions of Microsoft Visual Studio (Standard or Express) and using GCC via the MinGW environment. Things may also work under Cygwin, but that is not the preferred windows environment. Not all features will be available as well as with either Visual Studio or MinGW.
The file https://github.com/simh/simh/master/Visual%20Studio%20Projects/0ReadMe_Projects.txt describes the required steps to use the setup your environment to build using Visual Studio.
The file https://github.com/simh/simh/master/Visual%20Studio%20Projects/0ReadMe_Projects.txt describes the required steps to use the setup your environment to build using MinGW.
Download the latest source code as a zip file from: https://github.com/simh/simh/archive/master.zip
Unzip it in the directory that you want SIMH to reside in. Unpack it and set the file attributes as follows:
$ unzip simh-master.zip $ set default [.simh-master] $ set file/attri=RFM:STM makefile,*.mms,[...]*.c,[...]*.h,[...]*.txt
Simulators with ethernet network devices (All the VAX simulators and the PDP11) can have functioning networking when running on Alpha or IA64 OpenVMS.
In order to build and run simulators with networking support, the VMS-PCAP package must be available while building your simulator. The simh-vms-pcap.zip file can be downloaded from https://github.com/simh/simh/archive/vms-pcap.zip
This link will return a file called simh-vms-pcap.zip which should be unpacked as follows:
$ unzip -aa simh-vms-pcap.zip $ rename [.simh-vms-pcap]pcap-vms.dir []
The PCAP-VMS components are presumed (by the descript.mms file) to be located in a directory at the same level as the directory containing the simh source files. For example, if these exist here:
[]descrip.mms []scp.c etc.
Then the following should exist: [-.PCAP-VMS]BUILD_ALL.COM [-.PCAP-VMS.PCAP-VCI] [-.PCAP-VMS.PCAPVCM] etc.
To build simulators:
On a VAX use:
$ MMx
On a Alpha & IA64 hosts use:
$ MMx ! With Ethernet support $ MMx/MACRO=(NONETWORK=1) ! Without Ethernet support
