How to avoid to have some signals in test bench waveform


I am using waveform test bench of Xilinx ISE 13.0, but I don't want the following signals to appear in waveform.

#(parameter DATA_WIDTH=32, parameter ADDR_WIDTH=5, parameter F_width=18, parameter I_width =DATA_WIDTH-F_width, parameter CLK_PERIOD=2);

integer fileinA0,fileinA1,fileinA2,fileinXin,fileout, fileoutC,statusI = 0;

Anybody does know how to make dissapear this signals in thest bench?

 The integers works to open or write files, for example:
fileinXin = $fopen("Xargu.txt","r");

Thank you in advance!
