The manual is correct, they can be written at performance time,
but only once.

In fact they can be updated during performance as often as you like. 
Jonathan provided a working example in the manual which works fine, 
updating during performance. In order to get my example running I had to 
take out printks and use puts instead.

instr 1
k1 line 1, p3, p3
Sname = "number";
Sres sprintfk "%s:%2.1f\n", Sname, k1
puts Sres, k1
endin

Just so we're clear this doesn't work(why?):

instr 1
k1 line 1, p3, p3
Sname = "number";
Sres sprintfk "%s:%2.1f\n", Sname, k1
printks Sres, 0
endin

but this does:

instr 1
   kup line 0, p3, 100
   kdown line 30, p3, 10
   printks "kup = %f, kdown = %f\\n", 1, kup, kdown
endin

In one example printks works as expected, in the other example it 
doesn't. I'm afraid I'm still no nearer to understanding strings in Csound.

Looks like printks can't correctly print string variables that have been 
altered using sprintfk whereas puts can. Would others agree with this 
statement?
