I'm trying to change one bit of a byte in a subroutine, however the bit place may change. It doesn't seem like I can refer to the bit position with a variable. 

Simple example below. 
[code]
sub rtc_bit_change
' PARAM1 = Takes Byte address to change
' PARAM2 = bit position (0-7)
' PARAM3 = desired state
	temp4 = __PARAM1
	temp5 = __PARAM2
	temp6 = __PARAM3
	temp7 = rtc_read_byte temp4
	temp7.temp5 = temp6
	rtc_write_byte temp4 temp7
	endsub
[/code]

all variables declared as BYTES. (Though I tried changing temp6 to a bit, because that's all it is, and it still gets the same results). 

I get the error
'EXPECTED A VALUE BETWEEN 0 AND 7 "temp5"

I can't specify a hard value because I want to pass the bit postion as a variable so I can reuse this routine. 

Any ideas?
