how to declare a variable to present a text string ?

[chienpingwong]

I use statement below to load data for running simulation. I would like to know if there is a way can do to declare some variable or what, so that I can simply use it to represent  ../Sim/test_TB/CMD_packages/move_L2R.

#2000
file1 = $fopen("../Sim/test_TB/CMD_packages/move_L2R/cmds_10_reg_80.bin","rb");

#2000
file1 = $fopen("../Sim/test_TB/CMD_packages/move_L2R/cmds_10_reg_84.bin","rb");

#2000
file1 = $fopen("../Sim/test_TB/CMD_packages/move_L2R/cmds_10_reg_A0.bin","rb");

======================================

For example : 

declare PATH_1 as ../Sim/test_TB/CMD_packages/move_L2R

#2000
file1 = $fopen("PATH_1/cmds_10_reg_80.bin","rb");

#2000
file1 = $fopen("PATH_1/cmds_10_reg_84.bin","rb");

#2000
file1 = $fopen("PATH_1/cmds_10_reg_A0.bin","rb");

parameter PATH = "../Sim/test_TB/CMD_packages/move_L2R";
...
file1 = $fopen({PATH, "/cmds_10_reg_80.bin"}, "rb");
...

can I use similar way in including statement ?  or what is the right way to do it ? because what I put below isn't work

parameter TB_DataFile_Location = "../Sim/test_TB";

`include "{TB_DataFile_Location, "/TB_INI_CLK_nReset_2017_0109.v"}"

origianlly include statement is like

`include "../Sim/test_TB/TB_INI_CLK_nReset_2017_0109.v"

any suggestion on my problem above? 

Thanks a lot.

@chienpingwong try just `include PATH.

I don't think you can have predefined macro in include statement.

I try following statement, but it doesn't work. For your information. Anyway thanks for the help. It seems like macro cannot work on prodefine.

parameter PATH_1 = "../Sim/test_TB/TB_INI_CLK_nReset_2017_0109.v";

`include PATH_1
