Initialization of GENSYS

Search Path

The scripts in GENSYS are using an environment variable named $gensys, this variable must point to the directory where the GENSYS programs are installed. So before anything else can be defined in the $HOME/.profile_gensys-file the user must add the following line in $HOME/.profile_gensys-file:

#                                                                                   
 export gensys=<The complete address to the directory where GENSYS is installed>     
#                                                                                   

The $PATH variable must be updated with the $gensys/bin directory. In your file $HOME/.profile_gensys please add the following line:

#                                                                                   
 echo $PATH  | grep $gensys/bin > /dev/null || PATH=$PATH:$gensys/bin
#

Pre defined options for the programs in GENSYS

To the scripts in the GENSYS package, many command line options can be given. Values for these options can be stored in a file named gen_conf or .gen_conf. If not a local file can be found, Gensys will look for file $HOME/.gen_conf. If not file $HOME/.gen_conf can be found, Gensys will read file $gensys/bin/gen_conf.

Release numbers

The release number of the GENSYS package is a part of the name of the program, for example: gensys.. The reason for doing so is that several releases of GENSYS can be installed simultaneously. This open up the possibility for different users to run different releases of Gensys in the same computer cluster.
