s-save: will cause the state of the system to be saved at this point, and
     then continue the run.

q-save&quit: will cause the state of the system to be saved at this point,
     and then exit from the run.

Q-quit: will exit immediately without saving the state of the system.

m-misc: pulls up the miscellaneous sub-menu

c-continue: continue the run.

If you press 'i' for info, from the main TIERRA menu, you are able to select
one of the Genebank (GeneBnker = 1) data display modes:

> INFO   |  p-plan  s-size_histo g-gen_histo m-mem_histo z-size_query     |->

The second line from the top of the screen will change, providing additional
information on the operating system memory use, or the Tierrian memory use.
At the bottom of the screen, a new list of GeneBank data display options are
available.  All of these modes will try to provide as much data as can fit on
the screen.  These modes are detailed below:

Hit the c key to continue (to get out of this level of the menu)

The options are:

           p-plan  s-size_histo g-gen_histo m-mem_histo z-size_query

If you press 'p' from the info menu you get the Plan Display mode: 

>Now in Plan Display mode, updated every million time steps

This provides the normal statistics every million virual time steps
(this is also an easy way to clear the message area):

The meaning of this information is detailed above.

        5.6.1.2.1) The Size Histogram

If you press 's' from the info menu, the message area will show a histogram
of frequency distributions of the currently living size classes:

In the above histogram, the left column of numbers is the size class,
the middle column is the number of genotypes of that size class, and the
right column is the number of living adult cells of that size class.

        5.6.1.2.2) The Memory Histogram

If you press 'm' from the info menu, the message area will show a histogram
of frequency distributions of the currently living size classes, by memory
use:

In the above histogram, the left column of numbers is the size class,
the middle column is the number of genotypes of that size class, and the
right column is the amount of memory occupied by living adult cells of that
size class.

        5.6.1.2.3) The Genotype Histogram

If you press 'g' from the info menu,  the message area will show a histogram
of genotype sizes, by specific genotypes:

In the above histogram, the left column of numbers is the size and genotype
class, and the right column is the number of living adult cells of that
genotype class.

        5.6.1.2.4) The Size Class Information Display

If you press 'z' from the info menu, you will be prompted for a 
specific size class to examine, then you will get a list of the most
common genotypes of that size, with some statistics on them:

#    = acutal count, populations of adult cells of this genotype 
Mem  = is the percent of Soup, occupied by adult cells of this genotype
Err  = is the number of error flag commited,
Move = number of instructions moved to daughter cell,
Bits = Watch bits, defined in section: 7)  SOUP_IN PARAMETERS

0 values usually represent cases of insufficient data.

If you press 'm' for misc, from the main TIERRA menu, you will get the
miscellaneous sub-menu, which looks like the following in unix:

> MISC |  H-Histo Logging  I-Inject Gene M-Micro Toggle    |->

and the following in DOS:

> MISC |  H-Histo Logging  S-DOS Shell  I-Inject Gene M-Micro Toggle    |->

When this sub-menu is selected, some information is displayed at the top
of the screen about what variables are #defined:

VER=4.00 INST=1 PLOIDY=1  ERROR

This tells us that this is Version 4.00 of the Tierra program, we are using
Instruction Set 1, that it is a haploid model (Ploidy = 1), and that error
checking code is included.

From this menu, you have the following options:

H-Histo Logging: if you press the H key, it will toggle the logging of any
histograms you create to the tierra.log file.

S-DOS shell: (DOS only) this causes you to exit to the DOS prompt, while the
     simulator remains in the RAM in suspended animation.  You can now do
     anything that doesn't require a lot of memory.  Be careful that if you
     change directories, you come back to the current directories before you
     exit from the shell.  Also, be careful not to do anything that changes
     the graphics mode.

I-Inject Gene: inject a genome of your choice from the genebank into the
     soup of the running simulator.

M-Micro Toggle: turn on the virtual debugger.  The debugger has three states:
     delay, keypress, and off.  In delay mode, the debugger will execute one
     Tierran instruction per second.  In the keypress mode, the debugger will
     execute one Tierran instruction per keypress.

c-continue: exit from this sub-menu.

        5.6.1.2.5) The Virtual Debugger

The debugger has three main states: delay, keypress, and off.  In delay mode,
the debugger will execute one Tierran instruction per second.  In the keypress
mode, the debugger will execute one Tierran instruction per keypress.  Once
you have selected your mode, press c to start the simulator again.  You can
use this tool to step through the genome of a creature, either to see what
it does, or to debug a creature that you are writing.

In keypress mode, there are two additional modes.  Given that there is
usually a population of cells in the soup, the virtual debugger will swap
from cell to cell as each one gets its time slice.  However, this can be
disconcerting if one is trying to study the behavior of a particular cell.
The debugger can be made to follow a single creature using the trace option
as specified at the bottom of the screen in keypress mode:

      MICRO  |  T-Track cell  ESC-Main Menu  n-Next Step

If you hit the T key, you will go into trace mode, and the menu will change
to:

      MICRO  |  t-Untrack cell  ESC-Main Menu  n-Next Step

Now hitting the t key will return to the mode that swaps between cells.

If you wish to start debugging from the very beginning of a run, you will
want to start the simulator fresh with the menu activated, so that you can
start the debugger before the creature has started to run.  This is done by
giving two arguments when starting Tierra, one must be the name of the
soup_in file, the second is a dummy argument.  So for example, you should type:

tierra soup_in1 junk

The debugger display in keypress mode looks like:

InstExec  = 11,346072  Cells =  679  Genotypes =  274  Sizes =  26
VER=4.0 INST=1 PLOIDY=1    MICRO
