Xilinx ISE and Simulation

1. Variables in Xilinx ISIM
I'm Using Xilinx Simulator, so how do I get the simulator window to displays my variables? I have defined a variable as variable datacount : integer : 0;  

 but I dont see it in the Sim Hierarchy window, and cannot find out how to see the value of this variable along with my sim waveforms.

Ans: 

Variables are not visible simulation objects in ISim waveforms.  Status of variables can be observed using the command line / Tcl console using the show command.  Example:

show value <variable>

3.  Displaying Integers in Isim in decimal format

Currently, Isim doesn't support changing radix value of integers through GUI.

Soln: wave add -radix unsigned </path/to/integer>
