Also commented out my echo command as it's now a standard simh command
27-Nov-05 BLK Added Arithmetic Factor Register support per Carl Claunch (GUI only)
06-Dec-06 BLK Moved CGI stuff out of ibm1130_cpu.c
01-May-07 BLK Changed name of function xio_1142_card to xio_1442_card. Corrected list of
devices in xio_devs[] (used in debugging only).
24-Mar-11 BLK Got the real IBM 1130 diagnostics (yay!). Fixed two errors detected by the CPU diagnostics:
-- was not resetting overflow bit after testing with BSC short form
(why did I think only the long form reset OV after testing?)
-- failed to detect numeric overflow in Divide instructions
Also fixed bug where simulator performed 2nd word fetch on Long mode instructions
on ops that don't have long mode, blowing out the SAR/SBR display that's important in the
IBM diagnostics. The simulator was decrementing the IAR after the incorrect fetch, so the
instructions worked correctly, but, the GUI display was wrong.
>> To do: verify actual operands stored in ARF, need to get this from state diagrams in the schematic set
Also: determine how many bits are actually stored in the IAR in a real 1130, by forcing wraparound

* This is not a supported product, but I welcome bug reports and fixes.
* Mail to simh@ibm1130.org
* Update 2012-10-12 Added ability to specify tab expansion width in deck files
* Update 2008-11-24 Made card reader attach always use read-only mode, so if file does not exist
it will not be created as an empty file. Fixed bug in BOOT CR (cold start from card)
that resulted in seeing cold card data again when next card was read. (This caused
the DMS load deck to fail, for instance).
* Update 2007-05-01 Changed name of function xio_1142_card to xio_1442_card.
Took six years to notice the mistake.
* Update 2006-01-23 More fixes, in call to mktemp and in 2501 support, also thanks
to Carl Claunch.

*
* Simulator implementation will create a JPEG image corresponding to a
* landscape mode sheet of paper, the width of the carriage at 11".
* A diagram of more than 8" of paper travel will span printed pages
* in landscape mode.
* Notice that the WIDTH is 11" and the LENGTH can be anything up to 120'. And, the WIDTH
* was the plotter's Y direction, and the LENGTH was the plotter's X direction.
*
* The simulator creates a GIF image corresponding to a landscape mode sheet of paper. That is,
* the plotter's Y direction is the image's horizontal dimension, and the plotter's X direction
* is the image's vertical dimension. The WIDTH of the image is always 1100 pixels (11 inches at
* 100 dpi), and the LENGTH (height) of the image can be set. The default is 800 pixels (8
* inches at 100 dpi). A diagram of more than 8" in length (X direction) will span more than
* one printed page in landscape mode.
*
* When an 'att plot' command is issued a file is created based on the
* default or currently set values of paper length, starting
* position of the pen in both X and Y axes, pen color and pen width.
* Based on the number of logical pages of paper, the command will create
* the proper size canvas internally and create the output JPEG file.
* default or currently set values of paper length, pen position, pen color and pen width.
*
* When a 'det plot' command is issued, the plotter image will be converted
* into the file that was specified during the attach process. The
* image is not viewable until this point, unless an examine plot is
* issued which will dump the current state of the paper into the file.
* When a 'det plot' command is issued, the plotter image will be
* written to the GIF that was created during the attach process. The
* image is not viewable until this point. (You could implement an EXAMINE PLOT command
* of some sort to write out an intermediate version of the image, but this is not currently
* implemented).
*
* The 'set plot' command can set pen width, paper length, pen color,
* current carriage X and Y coordinates. Paper length can be set
* current carriage X and Y coordinates, as discussed below. Paper length can be set
* to alter the default of 800 (8"); changes are ignored until
* the next 'attach' command. The current carriage x and y positions
* can be set at any time and will go into effect immediately, just
* as the pen color and pen width can be altered on the fly.
*
* NOTE: requires gd library and definition of ENABLE_PLOT_SUPPORT in makefile or Visual C configuration
* gd is not included in the main simh and ibm1130.org distributions at the present time.
* NOTE: requires the libgd library and definition of ENABLE_PLOT_SUPPORT in makefile or Visual C configuration
* gd source is not included in the main simh and ibm1130.org source distributions at the present time due to
* licensing issues.
*
* NOTE: On Windows, you need to either:
* + compile both LIBGD and SIMH to use the static C runtime libraries, compile
* LIBGD to a static library, and link LIBGD into ibm1130.exe (which is
* what we do at IBM1130.org, so that gd is built into the version of ibm1130.exe
* we distribute), or,
* + Compile both LIBGD and IBM1130 to use the DLL version of the C runtime, and compile
* GD to either a static library or a DLL, but, static is easier since you don't
* need to copy LIBGD.DLL along with ibm1130.exe

*
* attach [-w] plot filename.gif
* Creates file filename.gif and attaches the plotter device to it.
* The file is empty at this point. The pen is raised. If the -w option is specified, and the
* simulator does not draw on the plotter between attach and detach, the gif file will be deleted
* on detach. (This is useful for the the cgi version of the simulator).
*
* detach plot filename.gif
* Detach the plot device. The gif data is written at this point, not before.
* If the -w flag was used on attach, and there was no plot activity, the gif file will be deleted.
*
* set plot black | red | blue | green | yellow | purple | lgrey | grey
* Sets the pen to the named color. Default is black.
*
* set plot 1.0 | 2.0 | 3.0 | 4.0
* Sets the pen thickness to the specified number of hundredths of an inch. Default is 1.0
*
* set plot penup | pendown
* Moves the pen up or down (onto the paper).
*
* set plot length NNN
* Sets the plot length (plotter X direction, GIF vertical dimension) to the NNN hundredths of
* an inch. Default is 800. The plot width (plotter Y direction, GIF horizontal dimension) is always
* 1100 (11 inches). NOTE: Changing this setting has no affect on the current plot. It takes affect at
* the next "attach plot" command.
*
* set plot xpos NNN
* set plot ypos NNN
* Sets the pen x or y position to NNN hundredths of an inch.
*
* (You cannot manually create a plot by issuing set plot pendown, xpos and ypos commands. The xpos and ypos
* settings only change the starting point for the simulated program).

Here's the 1130 simulator as it stands now.
Status: 25Oct2012
* Added plotter and 2250 GDU support (though, we don't
have the 2250 support library)
* Numerous fixes, especially the error in compiling
the FORTRAN sqrt() function under extended precision.
Status: 22Jul2003
* Added support for APL\1130 output translations
