Need unsigned integers

[ScarBelly]

On an FMD1616 the following does not work for me when Input 16 is used due to it reversing the sign of the input as a signed integer.

If (INPUT[1]  > 0) AND (INPUT[1] > DM[1]) Then
         'DM[1] contains the last state of INPUT[1] and I'm looking for additional inputs On.
    SetBIT Relay[1],0      
EndIf

Is there a simple way around this?  Could you consider adding unsigned integers?
Thanks

If you want to check for differences between two variables, then the best way is to use exclusive OR.

E.g.  DM[2] = INPUT[1] ^ DM[1]

DM[2] will only become zero if INPUT[1] and DM[1] are identical. Otherwise the bit that is ON indicate the differences between the two variables. This method does not depend on the order in which the bits are turned ON.

Unsigned integer is not supported. However, you may assign them to 32-bit integer and mask out the upper bits so that you can compare them.

E.g.  DM[1] = &H9000    ' this is a negative number
        A = DM[1] & &HFFFF  ' this will mask out the upper 16-bit of extended sign so that A = &H00009000 instead of &HFFFF9000

Thanks for the help
XOR won't help because I still need the 2nd greater than evaluation.
I was able to fix it using your 2nd suggestion.

A = INPUT[1] & &HFFFF
B = DM[1] & &HFFFF
If A <> B Then
   If (A  > 0) AND (A > B) Then   
       SetBIT Relay[1],0
       CLRBIT Relay[1],1      
   EndIf
'...........
EndIf
