Use the logical AND operator &&. For example

if(k1>0 && k2<10) then
bla bla bla
endif

This tests if k1>0 AND k2<10

You need the "Logical" AND operator &&


try:

if (imodwheel >0  &&  inote >isplitpoint) ...

By the way, there are some strange logical opcodes (and, or, xor) listed 
via csound -z1, even with different combinations of i/k/a-rates.

[...]
xor         a           aa
xor         a           ak
xor         a           ka
xor         i           ii
xor         k           kk
[...]

I haven't found anything about them in the manual and using them by 
trial ends up with a "no legal opcode" error. What's the matter with them?

Example:

instr 1
   k1 init 1
   k2 init 2
   kres xor k1, k2
endin

Best,
Jana

They are expected to be used in expression (infix) form
