I've been trying to use the goto statements to perform array processing, but 
it seems to me they only jump forward.

For instance, shouldnt this sco write the value 0 in positions 0-15 of zak 
space, for _each_ kontrol pass?

sr   = 44100
kr   = 44100
ksmps     = 1
zakinit   1, 16

     instr 1
kx   init 0

loop:
     zkw  0, kx
;    printks "X=%f\n", 0.01, kx, 0, 0, 0
kx   =    kx+1
if (kx<16) kgoto loop
kx   =    0
     endin

Uncommenting the printks, I expected to see values in the range 0-15, but 
instead they are always zero (the goto statement is not being executed)
What am I missing? how can I achieve the equivalent of processing a complete 
array of values for each k-pass? How do I process the values of a whole 
table (or a range of zak space positions) in a single k-cycle?
Should I use reinit for the loop-back part?

Thanks in advance, and sorry for the rather un-musical example
