Summary: conditional write to chn error

Initial Comment:
When using chnset inside a conditional (if ...then), the conditional seems to be skipped and the writing to chn occurs in all cases (regardless if the conditional is true or false).
Replacing the chnset with a k-rate assignment works, so it seems the error is related to chn.

Message:
This is expected behaviour, since chnset is polymorphic, giving it a
constant will call the i-time version of the opcode. If you change 1 and 2
for kval1 and kval2, it will work as expected.

instr	1
	kmetro		metro 1
	kcount		init 1
	kcount 		= kcount + kmetro
	ktrig1		trigger kcount, 2, 0
	ktrig2		trigger kcount, 4, 0
	kcount 		= kcount % 6
	kval1 = 1
	kval2 = 2
if ktrig1 == 1 then
			chnset  kval1, "test"
endif
if ktrig2 == 1 then
			chnset  kval2, "test"
endif
	ktest		chnget "test"
			printk2 ktest
	endin
