Might also look into 'range' as well, used in the '#switch'
definition. Although the already said '#while' method seems perfectly
plausible for the problem. Except I would put the last '#if' in the
middle instead, and include a 30 check also. I might be in error so be
warned.

 #declare counter = 0;
 #while(counter != 29)
     /*Do something*/
     #if(counter < 16)
         #declare counter = counter + 1;
     #end
     #if(counter = 16)
         #declare counter = 45;
     #end
     #if(counter = 30)
         #declare counter = 29;
     #if(counter > 16)
         #declare counter = counter - 1;
     #end
 #end // 30 check
 #end
