Indeed it is possible to bypass the normal startup dialog of EMME/2 and
enter a specific EMME/2 module directly. This is done by calling
emme2 with the corresponding 3-digit module number as argument
(no decimal point!). Most often this is done with the command
``emme2 000'' which brings up the EMME/2 main menu without asking
any initial questions.
Note that using this shortcut to enter EMME/2 should only be used when continuing to work with EMME/2 after having temporarily left the system for performing some other tasks. At the very beginning of an EMME/2 working session the system should always be entered normally with the standard startup dialog. This not only ensures that you work with the proper settings (devices, user initials, scenario), but also performs some consistency checks on the data bank which otherwise are not executed.
As a principle, never use the shortcut when working with a new release of EMME/2 for the first time on an existing data bank.
EMME/2 menu command are the commands that can be entered
at the level of the EMME/2 main menu, i.e. as valid answers to
the question Enter: Next module=. Normally, at this point
the user enters a module number, but there are many other useful
commands that are allowed at this level. Use the menu command
help to display a summary of all available menu commands.
Use the dim menu command. This command displays the current
data bank dimensions. Note that these values do not reflect the
actual number of elements currently defined, but reflect the space
that is allocated for these elements. These dimensions are specified
when the data bank is initially created, and some of them can be
modified later on using the macro MODIFYDB.
The current scenario can be changed using the scenario=
(or short s=) menu command. If given with a valid scenario
number, this scenario will become the new current scenario. If no
scenario number is given, a list of all existing scenarios is
displayed. In addition, if switch 6 is on (menu command on=6)
the user is prompted for the current scenario whenever she starts
a new EMME/2 session.
The menu command status (or short sta) can be used to
display a summary of the current scenario. This summary includes the
current network size and the current assignment status, including all
parameters used to prepare the assignments.
Use the page= (or short p=) menu command. This command can be
used to set the current page number to an arbitrary value. For each
subsequent report page generated, this number will be increased by 1.
Thus after the command p=0 the next report will start with the
page number 1. If no value is specified, this command simply displays
the current page number.
In EMME/2 a set of switches is available to control various aspects
of the system behavior. The switches are numbered from 0 to 31
(the are internally stored as a bit pattern) and they can be accessed
with the menu commands
on=X (set switch X),
off=X (reset switch X)
and switch=X (show status of switch X).
The command switch= (or short sw=) without switch number
displays the status of all switches.
In order to read in a new device table, switch 10 has to be set
with the menu command on=10 and then the EMME/2 session should
be terminated. The next time EMME/2 is started it up again with the
command emme2 (no shortcut to enter directly a specific module!),
the new device table is read and the user is prompted to select the new
terminal, printer and plot file device.
