[ns] Installation problems with ns-2.33

[harsh batra]

hi...i am new to ns so dont know much...but i know this problem can be
solved by setting the path.....with command PATH=EXPORT PATH folllowed by
the paths of ur standard directories......when u must have installed ur
ns...it must have given u a path which should be saved.....
now if that path is not saved properly...it wont allow u to execute nam file
directly as it doesnt know where it stores and u get the error of
$ ns: finish: couldn't execute "nam": no such file or directory
      while executing
"exec nam ptrace.nam &"
      (procedure "finish" line 6)
      invoked from within
"finish"

u can see the output by going to nam directory under ur ns folder
and open out.tr thru nam

and for avoiding the error set ur path to nam file

and plse anybody help me also...
i need a coding for a algo but i m cluless how to start....if anybody can
help me then i can communicate with that person and can tell u the algo to
be implemented...
pls help me
regards
harsh
