[chuck-users] can there be many ::ms in while?

[2g]

oh
maybe in the second way
am just looping the 1st while only?

maybe it was a bit too early for me to ask things on the list
(only i can do is modifying the tut)
i thought
100::ms => now;
was something like "100msec later do ..." or "every 100msec do ..."
but i happened to find that in () expression of while

mmm
i'll go through a bit more ahead in the manual
yes
then i'll find Blit-UGen waiting for me?
