Most installations of GPSS World are
automatic, or nearly so, requiring only a few mouse clicks. However,
some installations require that a registration form be submitted to
Minuteman Software.
If an internet connection is available,
chances are that the rest of the activation will be automatic.
However if email messages are sent, a numeric user key will be
returned for you to enter into a dialog box.
After you install a full version of GPSS World, the first time you launch
it you are asked to fill out an activation dialog to request a numeric key so
you can run the software. The next step is to send the automatically
encrypted message to Minuteman Software. You can press a button to do this
automatically (either via internet connection or via e-mail), or you can place the encrypted message on your system's
clipboard, and you can send it yourself to
activation@minutemansoftware.com.
If your registration is in order, the numeric key will be returned
the way it was sent--either internet connection or email.
For email registration, you must then exit GPSS World
completely. Then next time you launch it, you will be asked to enter the
numeric key. You can just type it in, or, if you click right on the entry
field, you can simply paste from the clipboard. Click OK, and you should be on
your way.
There are two common reasons for problems in expressions.
First, when expressions are used as arguments in GPSS
Statements, they must be placed inside parentheses.
Secondly, for historical reasons, by default, GPSS
World uses the # symbol to denote multiplication instead of *, which
is used for indirect addressing of System Numerical Attributes. If you prefer, you
can switch the use of these characters by changing a Model Setting.
If you do, * will denote multiplication, and # will denote GPSS
indirect addressing and can also be used to start a comment line.
