export PATH=$NS_HOME/tcl(tcl_verison_no)/unix:$NS_HOME/tk(version_no)/unix:$NS_HOME/bin:$PATH

export LD_LIBRARY_PATH=$NS_HOME/tcl(version_no)/unix:$NS_HOME/tk(tk_version_no)/unix:$NS_HOME/otcl-(otcl_version_no):$NS_HOME/lib:$LD_LIBRARY_PATH

export TCL_LIBRARY=$NS_HOME/tcl(tcl_version_no)/library

     EX: (Setting  Environmental Variables for ns-2.27)

export PATH=$NS_HOME/tcl8.4.5/unix:$NS_HOME/tk8.4.5/unix:$NS_HOME/bin:$PATH

export LD_LIBRARY_PATH=$NS_HOME/tcl8.4.5/unix:$NS_HOME/tk8.4.5/unix:$NS_HOME/otcl-1.8:$NS_HOME/lib:$LD_LIBRARY_PATH

export TCL_LIBRARY=$NS_HOME/tcl8.4.5/library
