Since T100MD does not support floating point, assuming you don't use more than 1 decimal place, then use a fixed point of 1 = 0.1

A = ADC(1)*10   ' every unit represent 0.1
A = A + 25          ' Add 2.5 to A
IF A > 5 THEN
   SETIO OUT1
ELSE
   CLRIO OUT2  ' do you actually mean to turn OFF OUT1 and not OUT2?
ENDIF

Not too difficult isn't it? Note that the output 1 and 2 should be defined as OUT1 and OUT2 in their label name table.

Thank you very much for your fast response.
but I have one question.

should the statement be

IF  a>50 ? instead of if A>5

Thanks
