I'm teaching Csound to undergrads this semester and they keep asking how 
to repeat a section without copying and pasting hundreds of times. I 
know about r statements but they don't let you play other i-statements 
until they finish. Generally what most of the students want to do is to 
lay down a drum beat first and then put down other things on top of 
that, for instance

r100; repeat for duration of track
backing track....
s

i"bass" 10 10;bass comes in after 10 seconds

I rarely use Csound scores for much, is there a way to do this?

the event stuff is eadier for a basic riff
Or use of #include and b works for fewer repeats

Thanks John, I didn't know about b.

Not sure if this would be helpful to you, but to define and then recall 
sections you can also use score macros:

http://www.csounds.com/manual/html/ScoreMacros.html

This wouldn't help much if you want to repeat a single section for an 
entire track but it is still useful to write a piece using patterns.

You can define a macro of several lines. You can also pass arguments to 
them (like the starting time):

; the macro defining the riff/loop/whatever
#define LOOP1(T) #
i1   [$T+0]   1   8.00   10000
i1   [$T+1]   .   .   .
i1   [$T+2]   .   .   .
i1   [$T+4]   .   .   .
#

; a macro calling the macro above 4 times
#define LOOPX4(T) #
$LOOP1($T)
$LOOP1([$T+4])
$LOOP1([$T+8])
$LOOP1([$T+12])
#

;and so on
$LOOPX4(0)
$LOOPX4(16)
$LOOPX4(32)
$LOOPX4(48)

Am I abusing macros, John?

Thanks Cesare, I just gave a class on this, pretty powerful stuff. 
Thanks for the examples, no doubt I will use them at some stage. In 5 or 
6 years of using Csound I've never explored the score language much, 
it's always been live stuff with me.
