sir
i have tried to execute wireless1.tcl file and have got following error

*$ ns wireless1.tcl$ *
num_nodes is set 3
warning: Please use -channel as shown in tcl/ex/wireless-mitf.tcl
INITIALIZE THE LIST xListHead
Loading connection pattern...
couldn't read file "../mobility/scene/cbr-3-test": no such file or directory
    while executing
"source.orig ../mobility/scene/cbr-3-test"
    ("uplevel" body line 1)
    invoked from within
"uplevel source.orig [list $fileName]"
    invoked from within

uplevel eval $buffer
} else {

    (procedure "source" line 8)
    invoked from within

*i had then moved wireless1.tcl to tcl/ex folder where on executing it i
have got output as*
**
*./ns wireless1.tcl*
num_nodes is set 3
warning: Please use -channel as shown in tcl/ex/wireless-mitf.tcl

Loading scenario file...

channel.cc:sendUp - Calc highestAntennaZ_ and distCST_
highestAntennaZ_ = 1.5,  distCST_ = 550.0
SORTING LISTS ...DONE!
NS EXITING...

please tell me
1. rather this output is correct or not
2. what i have to do in order to run all wireless examples without moving
them to tcl/ex folder
