The instruction at line 50 compares a and 0 and sets the flags accordingly. If a is greater than 0, then the control moves to line 53 which stores +1 at b, and if condition is false i.e. a is less than or equal to 0 then the control moves to next line, 52, from where it jumps to line number and program ends..
