Release Notes for Simplexus version 1.10
15 March 1994

These are some last minute advisories:

1. The Reset Sim menu selection and the the Reset button in the Sim clock 
MAY not work properly.   Reset sim is to allow you to run another simulation
without reloading  Simplexus.  Workaround:  reload Simplexus.  The other
reset on the Sim clock is to reset certain run-time and state variables
to delete an intial transient or "warm up" phase in the simulation.

2.  When saving a simulation, save it immediately after you create it. 
Although each execution re-initializes the state variables, so that if 
you save an object which is, for eaample "busy" it will be loaded as "busy 
it  is best insure that all state and run time variables are saved in their 
initialized state.  If you save your sim after running it, there may be some
undesired side effects.  

3. Simulation files saved with Intel-based Windows NT will not execute properly
on Alpha and Win32s platforms.

4. The return from the USERCODE.DLL is an integer.  There be a
bug in the Microsoft C compiler which prevents it from returning a valid
floating point number from a DLL.  I'm looking into it.  Anyway,the value 
desired (delay) should be a floating point number, so the integer return 
value is cast as a float on returning.


5.  Installation problems.  For Win32S installation, you must reboot into 
Windows 3.1 after the files are installed.  For 386 computers, the setup 
does this for you; for 486's you may have to manually restart Windows.

6.  Documentation.  See userman.doc for the MS Word version of the user's 
guide, userman.ps for the PostScript rendering, and userman.wri for the MS Write 
version. These may be compressed with PKZIP (tm) or with the Microsoft
compression utilities shipped with the win32s distribution.  If so, they
will be named Write.zip, etc.

7.  Graphics geometry for Connectors:  when a source node is moved, its 
connector to the target becomes disconnected at the target end if the 
target "y" axis is less than (higher on the screen) the the y axis on the
source.  Simply move or slightly reposition the target node to re-connect.

8.  The LANs need some work, especially as relates to backoff, contention, and the 
like.

ALPHA AXP
=========


9.  For Alpha AXP, the on-line report does not work-- invoking it aborts the 
simulation. For a workaround, just don't use it.  Use the automatically
generated hard copy report named sim.out.
