How to display even and odd number ranges between two given inputs.

Question

Hi Every one,
I am just started my career in sap abap and trying to find the solution for this.
I am trying to display number range using select options, but I am getting an error "Memory low leave the transaction before taking a break".
Example: when I give two number 2 and 10 , it should display set of all even and odd numbers in that range.
Below is the code logic that I am using:
data: a type i,
         b type i,
         c type i,
         d type i,
         num type i.
select-options: in for num.
a = inp-low.
b=inp-high.
c = inp-low mod 2.
d = inp-high mod 2.
while a <=b and c = 0.
write: "even numbers:', a.
b = a + 1.
endwhile.
while a <=b and c <> 0.
write: "odd numbers:', b.
b = a + 1.
endwhile.
Any help will be much appreciated.

This is your logic...changed:
data: a type i,
          b type i,
          c type i,
          d type i,
          num type i.
data: even type i,
       odd  type i.
select-options: in for num.
a = in-low.
b = in-high.
c = a mod 2.
if c is INITIAL. "It measn a is even
   even = a.
   odd  = a + 1.
else.
   odd  = a.
   even = a + 1.
endif.
* Even
a = even.
while a <= b.
   write: / 'even numbers:', a.
*  b = a + 1.
   a = a + 2. "The next even number
endwhile.
* Odd
a = odd.
while a <= b .
   write: / 'odd numbers:', a.
   a = a + 2. "The next odd number
endwhile.
