I'm having a little trouble with the Modulus operator or more specifically the __REMAINDER Aliases in SX/B v1.51.01

From the HELP file under Operators section: Modulus it states:


[code]

Note: The remainder of a division (modulus) is available immediately after the division or modulus operation. This code:  

 
dig10 = value / 10

dig01 = __REMAINDER

 

... uses half the instruction space of: 

 

dig10 = value / 10

dig01 = value // 10

 

The only requirement for using __REMAINDER (or __WREMAINDER for word values) is that the assignment to another variable must be the first instruction following the division or modulus operation. "[/2]
[/code][2]
In my code I'm doing the following:


[code]
<FONT size=2>
tmp1 = Year / 4      ' Step 1a. - get a quarter of the year 


tmp2 = __REMAINDER   ' Setp 1b. - save the remainder
[/2][/code][2]
If Year = 00 then I would expect:

 

tmp1 = 0

tmp2 = 0

 

But I actually get:

 

tmp1 = 0

tmp2 = 255

 

However If I change the code to:


[code]
<FONT size=2>
tmp1 = Year / 4    ' Step 1a. - get a quarter of the year 

tmp2 = Year // 4   ' Setp 1b. - save the remainder[/2]
[/code][2]
I get what I expect:

tmp1 = 0
tmp2 = 0

Could this be a bug with the __REMAINDER? Or am I not understanding this correctly?

Thanks
