1. Please Help ME figure it out
I can not figure out how to Take a sequence and print the sequence starting
somewhere in the middle going to the end and then jumping to the begining
and stopping where it started. I don't know how to explain it.
E.G.
sequence scale
scale = {"C"}, {"D"},{"E"},{"F"}
--some print routine
I need to start at say "D" (depending on the user's pick)and print this:
D E F C
This for a music scale program I am working on.
Thanks
Dave

Try something like this... (untested code)
<CODE>
sequence scale
atom scale_length
scale = "CDEF"
scale_length = length(scale)
procedure print_scale(atom scale_pos)
sequence tmp
tmp = scale[scale_pos..scale_length] & scale[1..scale_pos-1]
puts(1, tmp)
end procedure
print_scale(2)
<CODE>

not quite sure about your question but here is a solution to what i think you
want.
i assume one thing, you know the array position of where to start printing.
<un tested code>
sequence scale
scale = {"D", "E", "F", "C"}
printf(1, "%s", scale[2..length(scale)])
puts(1, "scale[1..2]\n")
</un tested code>
that should prints out:
E F C D
I just used sequence slicing.
hope that helps a little.

Dave,
This works, but perhaps someone's got a more efficient way.
Warning: I've been doing Java more than EU recently, so some of the syntax
may be off.
for i = x to length(s) do // s is your sequence, x is your middle index
// your code here
end for
for i = 1 to x-1 do
your code here
end for
Hope this helps.
