Try to initalize kfreq :

kfreq    init    220 ;***** initialization of k-var
kfreq line 220,2,440
aflute wgflute 30000, kfreq, 0.32, 0.1, 0.1, 0.15, 5.925, 0.05, 1

You must modify the instr in the following way:

;******** begin ********
;sinus.orc
sr=100
kr=100
ksmps=1
nchnls=1


instr 1
k1 init 16
k2 init 127
k3 init 127

kchn = int (rnd(k1))
knum = int (rnd(k2))
kvel = int (rnd(k3))
kdur = rnd(2)
kpause = rnd(1)
moscil  kchn, knum, kvel, kdur, kpause
endin
;********* end ************

... and call RTsound with the following command line:

csound.exe   -eYKQq    file.orc  file.sco

(also study carefully the RTsound readme file next time!!!)

I hope this will help you
