XIL_MAP_LOCWARN !!!!!

xil_map_locwarn

Hi All
I have a problem when i am trying to set pin No. in my VHDL file
I have tried by 2 ways :
1- I wrote the pin allocation in UCF file
2- I wrote the pin allocation using LOC command in the VHDL file
in Both cases i have the following Error message :

To bypass this error set the environment variable 'XIL_MAP_LOCWARN'.

My OS is Win2k so i go to the DOS command and wrote
set XIL_MAP_LOCWARN = 1

but the problem still exists
Can any body give me a hand

xil_map_locwarn=1

Open properties of MyComputer.
Goto to the Advanced menu.
Goto to the Environment Variable and set system variable XIL_MAP_LOCWARN = 1

environment vaiable xil_map_locwarn

I know that i shouldn't post thanks but realy i want to thank you because this was a big problem for me
