Not too late, what would you like the iskip to do,
exactly? I can work on it tomorrow.

Skip opcode initialization, so that new notes "take over the data space 
of the previous note". Look at the "original" opcodes (oscil etc); they 
all have it, always the final optional argument, typically either named 
iskip or iphs; in the latter case the special value -1 is the signal to 
skip init. Quite a few more recent opcodes have it too, but by no means 
all of them. The legato system is a very powerful one (see my chapter in 
the Csound book!), and well worth supporting wherever possible.

The opcodes have now a skip parameter: 0 (default) no skip, 1 skip
initialisation. I'll modify the manual as soon as I can.

I have actually done these changes weeks ago, when asked, but
forgot to announce.
