-DO_WHILE_VARY_NOT_IN_RANGE - When using while endwhile

Question

Hi all ,
ex : I need to print values 23 24 25 26  preferably integers using while and endwhile looping.
when we use do enddo condition the loop iterates 22 times to reach the processing logic .
Using while endwhile we reach the condition 23 in the logical expression ,  im doing it but im getting one dump when i enter ranges value.
somewhere im doing a mistake .. need hints ..
Thanks.
data : int type i.
RANGES SELTAB FOR INT.
SELTAB-SIGN = 'I'.
SELTAB-OPTION = 'EQ'.
SELTAB-LOW = lv_low.
SELTAB-HIGH = lv_high.
append seltab.
while ( l_val <= lv_high ) vary l_Val from seltab-low next seltab-high range seltab.
endwhile .
here lv_low and lv_high are the limits of my logic ..
Br,
Vijay.

Dear Raymond ,
Thanks for your reply .
// next iterations - l_val is lost somewhere in the program memory
Infact the problem is solved if you are using the code to add 1 value  inside the  while logic. My attempt was to get rid of those
extra iterations . 
l_value = l_low
WHILE l_value LE l_high.
" process value
  ADD 1 to l_value.
       if l_value between desired range . "processing block
         then do something here ..
      endif.
ENDWHILE
Now using the above we reach to the processing block only after l_value crossed 22 ref to my earlier example. SO there is no go around to land directly .. just curious ..
Thanks for your time ..
